Jim Sterling has another interesting take:

Basically: If you buy a game, you aren't complicit to the bad shit the publishers do, but don't hate on people that point out the bad shit the publishers does. He points to some alternative things you can do if you want.

Well, this really applies to everything. It is literally impossible to live nowadays without supporting shitty behavior from companies because they're pretty much all shitty. It is impossible to buy or use any kind of electronics without supporting slave labor.

Well, maybe some indies with five people aren't that shitty.

Someone is trying to convince himself that buying yearly sports games from Electronic Arts isn't too bad.

Most indie developers aren't even vegan, so how can you trust anyone of them

Some make pixel art, that is better than veganism.

I can't trust people who are afraid of high resolutions.

I dont know what is the fixation this site has with Jim Sterling tbh, I think the guy is a bit intense and obsessed over certain topics and he is not a particularly good reviewer. Regarding this topic in particular, for me personally: I dont care.
If Blizzard wants to pander to China while they are being scrutinized by the rest of the world and i wanna buy a Blizzard game, I'd still buy it. 
If Konami was treating the entire MGS team as shit but they were gonna release a new Suikoden o Castlevania game, I'd still buy it. 
If Capcom wants to put already included characters behind a paywall, well I wont buy that cause thats too much. 

Speaking in general terms like you are, thats every company of every industry ever in the world in every single branch of commerce. That doesnt make them "shitty", that is literally whats needs to be done for a company - any company - to exist. 

It all depends of what you call shitty companies... but I don't buy games I consider shitty.

It is basically a matter of finding the company which the greed and interest give you the better product for your need.
