I've had the opposite experience. Facebook's been actively unfollowing and hiding my political groups for me. Every few days I have to go through a list of pages, check to make sure I'm still following them, and interact with posts to keep them in my feed.
that seems like the point where you'd stop using facebook, when you're altering your behaviour to appease the algorithm, because it won't just let you control what you want to see anymore. although i admit I also open all youtube videos of categories i don't intend to watch regularly in private tabs
It's been an issue for quite a while, but it's becoming unbearable since they started really clamping down on 'extremism' (left and right) around November. Unfortunately, there's no tool quite like it online for getting access to such a wide swath of firsthand knowledge, opinon and experiences.
Twitter has an option to just skip the algorithm and let you drink from the firehouse - switch to timeline view and put everyone you are following in “alarm” mode (otherwise, they’ll filter it as THEY see fit).
Most of the people I care about post on both, and when there’s an important long form article they post a link to it (whether on Facebook or their private blog)
Interestingly, youtube did that on me for some time, then it stopped. It repeatedly unsubscribed me from channels I used to watch more often, but kept intact some subscriptions I didn't visit regularly.
Facebook, by its turn, added some friends on my behalf. I was surprised some times to see a notification like "John Doe accepted you friendship request", but I'd never sent on. They also stopped doing that.
