There are many good and great games on the platform, and there are many more bad games that make the good games difficult to find. This is a common issue on platforms like this. If you dig hard, you will find some gems, eventually.
The trends are created by the game creators, and by the site's management, who feature the kind of games that they like. Game creators also notice what kind of games get featured, and then make more games like that in an effort to get featured. If you don't like these kind of games, I think that the people that run the site don't care about that. A feature to exclude multiple tags from listings is requested quite frequently, and it gets pretty much ignored every time. The closest to an official response you will likely get, is someone that likes to pop into the conversation and attempt to convince you that you don't really want this feature. Most people who don't share the site's ideology have given up, which is more bad behaviour.
There does not appear to be an easy fix to this problem. There is a hidden feature to exclude single tags, but there is more than one prolific tag filled with garbage. At the moment the solutions are limited to spending time digging through the aforementioned garbage, or to find some third party means to fix it, for example: Write a script to fix it, find another platform, or make your own platform. As you can see, there are no good solutions at the moment. I do suggest to those that disagree with the site's ideology not give in to apathy, and make their own opinions heard, even if it is just for the record. The world is in a bad place, and a lot of work and determination is required to fix it. Be part of the solution.
