Since this change is entirely a result of the bad behavior of the maintainer and would not have happened otherwise, this a perfect example of why we fundamentally cannot separate the work from the people who make it.
Even if you do not agree with the social backlash this person is getting, that backlash has real effects on the work.
I, for one, no longer trust that hyprland will remain a well-maintained piece of software given that the maintainer would rather increase their maintenance burden and diverge from using common tools instead of cooperating with the community.
Your best bet is to just avoid the need altogether. I use an nvidia shield with clipious, smarttube, and jellyfin. There is a qobuz app that is okay and a USB Media Player Pro that is pretty bad. I haven't tried any apps for subsonic streaming.
I'd bet there is a tidal app, but I think tidal also integrates with Plex?
For when I want to "cast" a random video file, I use VLC on my PC and on my shield to stream to the TV, and it works well enough.
I haven't found a good solution to have similar functionality as Google cast for other people to use, but none of my guests have ever been upset that it wasn't available.
