Earlier quoted context omitted.
I think the OPs point is that there are very valuable first-party sources of information with RSS feeds that you shouldn’t ignore. Basically, there is gold out there.
Facebook and Twitter both used to have RSS feeds, and stopped supporting RSS to force people to use their ad-heavy client interfaces. But that's not where the good stuff is. While "social" has dropped RSS, it's still doing great for real news.
But I hear you. I find Twitter unusable without 3rd party client, and I think that is affecting my experience in an indirect way as well. I think the fact most people see ML picked tweets has caused fewer people responding to what I share now versus 4 years back.
