I used to use it years back. Some subreddits were really great but they all inevitability devolved so I lost any interest in maintaining active accounts there. r/skookum had really interesting content for a while but devolved into idiots reposting the same skookum brand wrenches over and over again.
The For You feed varies week by week but is generally okay. I make heavy use of lists, mute words, etc to clean things up.
X is a train wreck, but an interesting and useful one, depending on who/what you follow.
I bought a premium Prime account on Amazon, and yet some of their shows still have embedded commercials. grrrr.
Plus, I get constant ads to upgrade to Premium+ for ads-free.
Premium+ is probably what you have.
The very second the US election got underway all of our accounts started to heavily promote right-wing political content. Even though we specifically said when we signed up that we aren't interested in anything like that.
I haven't gone out of my way to restrict my timeline either, I follow ~1000 accounts I just don't follow or interact with accounts that post any of that crap.
And whether their ideas and strategies are well-grounded or seem optimal or ethical to the rest of us, the top leadership at most of those companies lean strongly towards corporatist, libertarian political ideals and see most regulation (and preemptive self-regulation) as both philosophically immoral and an existential threat to their businesses.
Before I deleted my Twitter account, I tried really hard to just block every account that posted content I felt was pol-tier.. it just doesn't work. That platform is FUBAR, and the prime example is the owner of the platform who has been completely brainrotted from staring into the orb for 12 hours a day.
It seems like public sentiment is trending towards rolling over and letting channers run society. We'll see how that goes.
I will rail on FB just as hard as the next guy, but realistically, from a business perspective, if facebook's wild popularity and 3 billion active monthly users still says "unusable" to you... well, do you really think most people would agree with you? And more importantly to the company... whose opinion matters the most?
