I can definitely sympathize on a few levels with the people who do say things like buyer beware and: If you made an uninformed decision you "deserve" whatever consequences and shit you get for showing such a lack of responsibility with your own resources.
In not just video games but with all things you SHOULD beware, that goes for all commodoties.
Its healthy for a consumer in the long rong to actively seek out information that they can base certain choices on, because companies all over the world will stretch the truth on what their product does or doesnt do and yes while that is utterly disgusting practices that we've somehow just become apathetic towards with a "thats just how it is", its still something i believe can be changed and that you for now still have to adapt somewhat by being a responsible consumer in anything you do.
On the other hand just like this video points out: You shouldnt need to always at all times have to tread through a minefield or dig through a pile of dung just to find a hidden gem or the genuinely trustworthy and good companies and products that are upfront and transparent with their practices and who has the interest of the costumer as their primary priority, providing all the necessary information upfront to the consumer and being honest with their products or services.
Steam is in dire need of quality control and so are a lot of other things, you shouldnt need to become a brittish cynic in order to see that undeniable fact.
On a last note i believe the responsibility falls partially on both parties, not equally though, but enough so that one side definitely can do something about this kind of disgusting lack of quality control going on, every bubble will burst eventually but we can speed that process up severely as consumers, even though we shouldnt need to because this is a problem created by the industry in the first place but being held up by uninformed costumers so the sad truth is: Vote with your wallet.
