I think it's interesting to talk about how Steam recommendations works but I don't think they hold any value on their own.
Yeah. New generation kids grew up in internet culture therefore it reinforced a blindness towards how "fake" internet is. They don't notice how fake it's because they don't have real life experience. They don't get to learn from real people to comprehend how some reviews are obviously fake. But I don't mean "hater" comments at all.
People don't know how reviews are manipulated. Official reviewers getting paid for high score by the developer and the video game console companies but rivals also pay for negative reviews. Often when reviewers themselves asks developers for money and they threaten for bad reviews and when they are refused they write a nonsense negative review. It can be also another personal thing like "I just hate their games", "they banned me from their Discord server" and whatnot lol.
In that context it's a thing that companies offers "fake accounts" to their employees and their families just for positive reviews. Another aspect of it is they order Metacritic to delete negative reviews. For example CyberJunk 2077 initially had 5/10 score on Metacritic. They had to fake it a lot and then they released anime BS to boost sales.
Steam is no different. In the name of "preventing review bombing" they also block genuine negative reviews. It doesn't make sense. Their definition for "useless negative reviews" doesn't mean anything. When a company, after the game was sold years ago; enforce 3rd party launcher, necessary online login system or block you from playing it of course they deserve to be review bombed, not for negativity but just to warn people.
Another aspect of it is again tied to social media. For example Reddit and whatnot fascist internet communities teaches kids that "you either should go with the majority or your whole existence is ignored.". In video game context for example you get banned when you say you dislike FF7. This created a cancel culture internet suffers from. And then they invented "you complain" BS. In the end new generation kids became a mindless masses who believe they necessarily have to like what is popular, otherwise they believe their existence is trivial enough to "ban them". This is very different from how trends work for example. When something was a trend people used it, it became part of their life but when someone didn't care about it it was okay. Now everything is fake, everything is a show, everything is "black and white", everything is a BS philosophy just to justify BS lol.
So when I see a video game selling well just because of its popularity all I see is kids believe the driver of the so obviously suspicious van that state "free candy" with lots of colourful lights around it is a trustworthy guy who wouldn't kidnap them for their organs. Fundamentally, since city life offers protection, the type of people who would be easily killed on their own are prevented to be killed by natural selection, so these people are easily scammed thanks to the internet. This is all I see lol.
