I believe what new management did with GPLv2 is technically illegal (Leaking telemetry to law enforcement / PG-13 etc), what forks are doing is technically just bring things back to where they were / should be with GPLv2, and forks are definitely legal .
Indeed, teams are forming, it’s little to early for now.

Yes, it’s legal to distribute Audacity or any derivative of it under either GPLv2 or GPLv3. The only thing that might be of questionable legality is the age restriction that the Audacity’s owner company is trying to impose. I’m not sure about that.
So, did you guys switch already? I will, not just because of the “controversy” but also because Audacity is buggy for me lately.
I just watched the video @keybreak linked and I guess I will choose Tenacity 'cause they keep the way how selections are marked while Audacium seems to have changed this. But from the video it looks like both are good alternatives and both seem to have a lot of contributors.
