I'm not sure why you feel like it is abandoned. There is a steady release cadence and the changelog[0] clearly shows that much is being worked on.
Because it feels worse and more broken as time goes on. Just like any other abandoned web app, except it's being made worse and slower as an active, deliberate, ongoing choice
yes of course there's progress and new features and it's not really abandoned per se.
but the feeling is that the outdated or simply bad decisions aren't fixed or redesigned.
it could be made 100 times better.
