I think Youtube has ran its course. Google knows Youtube is no longer the money maker it once was, and is knowingly (either literally so, or by using algorithms they can blame and plead ignorance) pushing spicy content to get you to interact.

This isn't a zero sum game: every time you tell it "don't recommend" and "not interested", that is an interaction, too. You are on Youtube instead of some other website or service. This is the attention economy equivalent of a loss leader.

If you believe Youtube no longer serves you, quit. This goes for any other service, too.
