I don’t think this is inherently a bad thing. It helps you find things you may be interested in by using statistical analysis. I think the problem is when it’s designed to maximize your engagement or to cater you towards specific content they are trying to push

Some hashtags “algorithm” like Mastodon does would be nice, but I think it is very similar to your subscribed feed already, but it could work for something like “powering up” your interests.
