It just goes to show how the internet represents such a small percentage of gamers and how a tiny vocal minority can make it look as if 'everyone' is having problems:

Hello Games’ No Man’s Sky can be seen as one of the most anticipated games of all time in the video games industry, and since its release, players have had mixed opinions about it.

Part of the reason people had mixed opinions is due to poor optimization on PC and a delayed release, with PS4 players reporting issues as well. However, Hello Games’ Founder Sean Murray tweeted out that “less than one per cent of players have raised support issues.”

Well, your OP is actually a good example of how everything becomes a fact on the internet just because you posted it :)
I own the game on PC and I have a really good PC (i7, Titan, 32gb) and the game is just bad at many level.

- Framerate is a disaster
- There is not so much to do in general; I mean yes you upgrade your gear, get the Atlas passes and even create (discover) your own galaxy but at the end all planets are pretty much the same
- The planets are just way too empty.

There is no way, only 1% are unhappy with the game; maybe only one % reported it (and I doubt that too) but a lot must not be playing the game anymore or got a refund.

Where did the dev say only 1% are unhappy with the game?

The vast majority of people that have issues do not report them, basically for every 1 that reports a problem there will be another 10 others that do not. I will probably buy this game in a few weeks when more of the kinks are ironed out.

Nowhere, yet that's exactly what they are suggesting by saying that.

Is it?  Interesting.  I read that less than 1% have raised support issues.  That says absolutely nothing about their emotions towards the game.

By saying that they want the reader to think everything is going perfectly but there is a very tiny minority on the internet that makes it looks like a big deal. 

By saying that they want the reader to think everything is going perfectly but there is a very tiny minority of unhappy users on the internet that makes it looks like a big deal, the rest is fine. In reality that couldn't be far from the truth as the problems with the game seems to affect most of the owners, specially on PC where is a mess.

Nowhere, yet that's exactly what they are suggesting by saying that.

Ahhh you again! I don't think I've seen you in a Sony thread without having a little dis. You've certainly upped your game for NMS.

OT: So here, context is key! Let's take a look because a lot of wild claims and assuptions are being made.

Let's take a look at what was said.

I think it's pretty clear he's talking about their customer support that they've set up to handle these issues.

First Sean mentions that they have hired a customer support team that is bigger than their developing team, they then create a page for people to get help and support. They tweet this;

"Even though less than one per cent of players have raised support issues, we're going to resolve roughly 70% of them this week"

this

"It's pretty crazy for us how many people are playing. And how large a number even 1% of that user base is."

and this

"We're totally focused on customer support right now. Then we'll move onto improving and adding features to the game "

He's clearly talking about issues raised to his support team.

But granted it should of been sorted pre-launch. 1% is still quite high considering everybody with an issue will not bother contacting them for support.
