Something being borked by the official Fedora packagers versus something being borked by some random AUR user are not even remotely similar.

Firstly, the AUR is officially unsupported by Arch, so it’s not really their fault or problem. Secondly, I would guess a majority of AUR packages are not officially supported by software devs either, so the dev in question can go ahead and drop support if it’ll give them a good enough reason to start filtering out the low-effort bug reports. It just seems like an overreaction over something that amounts to a miscommunication.
