Steam is a private company and has the philosophy that they do not want to tell you what you can/cannot buy. 

What is quality to someone, will be garbage to another. it is a subjective issue, not an objective one. 

And here it is :)

Actually I am not at all. If it were all or nothing then explain consoles? Consoles wade through the games that want to be on their platform and (mostly) get rid of shovelware. 

Content that some may find offensive SHOULD NOT be blocked

Content that is not finished SHOULD be blocked. 

Some people seem to think Valve could afford to hire people to curate Steam, and I'd be stunned if they weren't absolutely right. However, I think that shows lack of understanding the situation. I think Valve doesn't curate Steam very much not because they're cheap or some other bizarre 'explanation', but instead because Steam is huge and Valve feels like curating Steam heavily would be unfair and potentially problematic from a freedom of speech point of view (but mostly unfair). Sales will handle whatever curation is absolutely necessary, and Valve simply needs to provide the tools so that players can find the games they're interested in. Mind you, I think the tools have been quite lacking, and I'm hoping for improvement.

Except they are limiting it to "trolling/illegal", and not "everything".

They set the bar lower than most, and even then, most out there are subjectively choosing what they think is "quality". 

They have apparent competition from the likes of GoG (but then again, that storefront blocked a popular dev's puzzle game based on the grounds of it looking like a "mobile game"), B.net, Beth.net, Uplay, origin etc. if you think those aren't all within competing with one another, then you should take that up with others on the forum here.

I'm not sure how denying more games, more "selected" games from a small group (yes, it will always be small no matter what universe or angle, because there are millions more consumers than there are those that can serve and judge) would be better for all of us (myself included) and cause me to stay with Steam and not choose another's storefront.

I already see myself not using Origin, because all it has is Battlefield, the only series I'm interested in at this point. EA did a bang up premium job of killing off C&C, Theme Hospital, Sims, SIm City, Dungeon Keeper, Battlefront and more for me.

I hardly bother with Uplay due to buying games on Steam requiring yet another client to run, and even then Ubisoft games come loaded with extra DRM that bogs down my overall performance. I'm essentially buying higher priced games from them, only to net myself a worse off experience, and a neutered one at that. 

I don't use Beth.net because what they have on there is found on Steam, and Steam has built in mod support and is just better than beth/net

I don't use Epic's client because I dislike what Epic have become and who they are now controlled by.

I hardly use GoG because it doesn't really have the games I want, let alone mod support, built in forums and a vastly better wishlist/gifting service. 

yes, Steam has garbage, but to me, so do a lot of the other storefronts, and a lot of those storefronts have lesser features, while also at times asking for money money for a lesser experience. 

If I am to ever pay for a Ubisoft game at it's highest price, and use it on a beastly PC, I expect the Royal party treatment, not a watered down experience for more money. That is never how that should work, yet it does with Ubisoft countless times. 

For me, I wouldn't want to set a bar for quality control, because I know that others out there would disagree with it.

In 99,999% of the cases those assets are not stolen, but freely available with the engines or on the stores of those engines.

Showelvare is not trolling by any definition. Straight up trolling would be a game where the only theme is to troll somebody, like for instance a game where all you can do is produce pelt totalbisquit or Jim Sterling, but not Shovelware. I mean, f***ing Aids Simulator is not even considered trolling by Steam, even though it admits it's a short, bad, asset ridden game. Just look at the game's "features":

Features:
- Asset Flip
- Very short
- NO NUDITY
- Poor performance
- First-person shooter
- Zero effort cash grab

I literally copied that from the storepage of the game. If that's not trolling yet, then you can't consider valve to consider all the shovelware as trolling either, not even by a longshot, country mile and then some added exponentially on each other

In short, what Valve is doing is opening the floodgates even further than ever

Nobody needs to buy those games for them to be profitable on Steam, and that's the problem. They are financing themselves through the Steam trading card system by basically selling those to the card collectors

Also, the problem isn't only buying or not - try finding something you don't know the exact name of when over 100 games get added per week

I really do have to feel for Steam though. People are going to complain no matter what they do. Though I guess they brought this upon themselves since they have never had any kind of quality standards now people will look at anything they do as taking games away (even if they are garbage). Then there is people like me who will complain that the average quality is extremely low and needs to be improved.

They are in a lose/lose situation at this point

But you are. Shovelware is some kind of content, like it or not, so getting rid of any kind of active curation (they'll review a game after a complaint has been filled) will only make it easier for this kind of content to appear on the store, making it worse.

Consoles wade through (nice expression that I didn't know! Thanks :) ) shitty games because they do curate the games for their consoles. Devs/publishers ask for permission to release their games and Nintendo, Sony and MSoft decide, after inspecting it, if they give the green light or not. But that curating is what Valve will get rid of, so as long as someone pays the $100 needed to publish a game on Steam, they'll be able to launch their games on the platform.

That's why being happy with this change and asking for no shovelware are almost mutually exclusive, it's impossible to have both things at the same time.

It is not, if Steam did like the console makers (but somewhat more open about content, as Sony, MS, and Nintendo are all pretty against explicit sex in games) and inspected all of the games for a certain quality then the issue of shovelware would be eliminated. The type of content should not be block (sexual, extreme violence etc.) but garbage shovelware games should be blocked. But why should Valve do any of this? It would be very difficult for them to implement all of this and Valve rakes it in hand over fist with Steam. PC gamers have allowed Valve to do and get away with whatever they want for to long.
