RSS harkens back to a time in the internet where you had to go out and "subscribe" to individual websites.
You didn't have monolith websites with their algorithmic feeds and internal mechanisms for following/notifications. RSS is literally a chronological feed of every individual website you've subscribed to.
And the good thing is that YouTube has RSS feeds. You have to go and view the actual source of the channel page - but if you Ctrl+f for "rss" it is there and does work. So I moved a lot of the channels I actually like to RSS, and left the algorithm completely.
You can turn most of anything into an RSS feed, there are tools that even turn websites that don't have RSS into RSS feeds. But a lot of indie sites have RSS feeds because it's a very cheap way to allow people to "subscribe" without needing to implement that as an actual feature. It's great because you control what you get notified about and see. You have to go away and add the link to your feed manually so it gives you time to consider if this is someone that you actually want to follow.
It has also just been a great experience looking up indie blogs and adding them to my feed. A lot of them have a "friends"/"recommended" page - but unlike algorithmically-generated ones these ones are hand made by the site creator. It allows you to spring right into another person's blog and consider adding them to your feed too.
I think RSS could curb a lot of the negativity that algorithms can push you into if they're geared exclusively for views. Negativity sells! Baa!
In my case, I tend to avoid a lot of negativity anyway - I watch long talks about programming and cybersecurity, and analysis videos on programming languages. I don't really have a reason to view negative videos (yet I still get recommended them, strange). RSS for me has been less about avoiding clickbait-y negativity and more about filtering low-quality off-topic posts/videos from the feed. It's a slower experience - the individuals who I've subscribed to are busy people and don't post super often, but it means when they do post I know I'm going to want to see it. For this reason I think that RSS is a great tool for screen time.
If you run a smaller blog website, add RSS. You'll get a handful of people who really appreciate it.
