It’s probably majority network effects. If you compare Instagram to 5, 10 years ago on the dot, you see an atrocious drop off on quality and usability. The change was so insidious, majority of people didn’t notice or care all that much. And yet, Instagram is still one of the largest platforms in the US, despite how objectively horrendous it is to users.

I had to ditch nextcloud after it started corrupting all of my files’ time stamp meta data. I really miss it though. Syncthing is what I’ve been using.
