Absolutely this. When I finally bit the bullet and downloaded TikTok, I was on it for maybe half a day before I gave up because content discoverability on the app is absolute garbage.
One of the reasons I've stuck around on Twitter so long is that their search features are incredibly useful compared to most modern social media sites. They allow users to get a much broader picture of what's actually happening as opposed to feeling like you're just silo'ed in your own little bubble. I think that has further effects on the ways that community is created and content is gamed. I've noticed the same thing happened on Instagram as it grew more popular. The explore feed is full of content that is obviously designed to play the algorithm rather than being actually useful to users.
