AFAIK: Development at AMD funded the dev to make it support AMD GPUs (instead of the then-supported Intel GPUs), Dev keeps a clause saying any and all work will remain open even if contract is cancelled, work is then halted by AMD and dev releases his updates on his repo, Legal then says later that the clause was not legally binding and can’t be enforced or such, making dev rollback to earlier Intel version
Trivago? Hotelikely.
