OK sure, if you want to be technically correct, “the algorithm shows you what you engage with” in some sense, but not any useful sense. There’s no proportionality.

As I said above, if you engage heavily with content you like that is outside of the mainstream categories the algorithm has been trained to prefer, it will not show you more of those things.

If you engage one single time, in even the slightest way, with one of those mainstream categories, you will be seeing nothing but that, nonstop, forever.

The “mainstream categories” are not publicly listed anywhere, so it’s not always easy to know that you’ve just stepped in one until it’s too late.

You can’t engage with things you like in proportion to how much you care about them. If something is in a mainstream category and you care about it only little bit, you have to abstain from interacting with it at all, ever, and don’t slip up. Having to maintain constant vigilance about this all the time sucks, that’s what pisses me off.
