Like I know this isn't a shock to anyone. But it's a super surprise to me. So since 2011 I was really busy with various educational or work stuff, and never had time to log in. When I did log in to post something random for family to see, I had that Fluffbusters extension that cuts out the extra shit that Meta adds to your feed.
So recently I was forced to use the FB app to do some IRL stuff related to Palestine. Holy shit the unfiltered site is garbage. You have to scroll through 10 or so unrelated pages to see your friends' posts. And the sheer volume of paid Israeli stuff is mind blowing, despite me trying to tell the algorithm that I don't like it. And despite me being friends with and liking shitloads of ML stuff, I keep getting Unilad level "let's save a bunch of puppies" content. Like I get why people who use traditional social media become liberals or worse, I even found myself becoming a bit more lib looking at it.
I recently cut down on my time on facebook when I got logged out of it and didn't bother resetting my password. But even when I was using it it was such a fucking cesspool. I had made an effort to block out content from pages I didn't like, but I would still get a ton of right wing posts.
