Meh, this borders on victim blaming. You can't deny they've done something to turn it the last few years. And there is no one of my interest left to follow, they've all jumped ship. I checked the "following" tab now, and there is nothing of interest there, they've all left.

I signed up a year ago, so I would not know how Twitter behaved back in the days.

All I am saying is that if you Follow accounts you are interested in and like a few relevant posts, the platform likely becomes quite usable.
