They may have been hit by something entirely unexpected and may still need to get their bearings. "It's not github, it's not a DCMA takedown." may very well be the only thing they can communicate with a modicum of certainty at this moment.

If what you say may have legal implications, it might be wiser to just say "no comments" for some time, while seeking proper counseling.

"Not DMCA" and "not GitHub" is plenty already. But maybe it's a possible malware infiltration, or having something unbecoming committed to the repo by mistake, or anything else that might warrant denying public access for some time to prevent damage.

There are a million reasons not to say something, and a blush of legal anything should deter you from opening your mouth in public before you're straight with a lawyer.

I think protecting themselves from being sued into oblivion is more important than getting a message out to users an hour earlier. We don't have any form of SLA agreement with Ryujinx

Also the project is being shut down. Why should they care about community reaction?

Why do I get so many inane responses every time I post here? Does it really take 5 people? It's impossible to respond even if I wanted to.

If and only if this was their intent and timeline. May be external.
