That's due to content creators, not YouTube.
YT pressures content creators into doing all sorts of stupid shit. They are made to think they don't really have a choice unless they want to risk their monetisation.
One memorable particularity was YT prompting the content creators to make thumbnail images with grimacing faces, which IMO is cancerous. yt/user/theCodyReeder talked about it, but I cannot find the video any more, this was about two years ago.
If I want to see a video I have to read all titles and it gives me a chance to think if I want to stop watching.
An added bonus is that it takes me at least a couple seconds to find a video to watch when I open the front page and I don't end up subconsciously clicking the first interesting thumbnail.
PS: Also let me add that I'm using youtube signed off with no cookies in a browser that doesn't remember history so the front page is usually the same videos that I don't want to watch for a couple days or a week at a time.
