It's still true, though. If they really don't want people to speculate on why they did something, they can provide a reason. It doesn't require an entire PR team to figure that out.
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?
This, a hundred times over. It turns out that communication isn't entirely a bullshit field of study* and it requires significant planning and effort to keep people happy.
* note: all fields have bullshit; this is a recent learning of mine -- unlearning, rather, of a single day of a communications class which left me with the impression that many of us here seem to have of soft sciences: all bullshit by default.
