They could at least put it in read-only mode for a short time and allow downloading of extant community content prior to a scheduled "reset day".
This smacks of flailing leadership and zero respect for their target user demographic.
The only sustained business I'm aware of is Hodinkee.
From what I can tell Watchville was abandoned a few years ago.
Their plan is to make the internet what is was 22 years ago.
I'm sure it's impossible, but what if it's not?

I use mander.xyz, it's science focused, but they also have a policy of only de-federating instances that host CSAM.
Their /instances page also only shows a single blocked instance, whereas something like programming.dev shows lots of questionable instances blocked.
If you're telling me it's _worse_ than reddit in this regard, I can only imagine how terrible it is.
Next time try doing it in a way that you control it.
My main point wasn't that, though. It's simply a bad and low-effort way to handle the situation, and like one of the other replies points out, there are better options. They could have just as well disabled posting and maybe even viewing of submissions and communities for the time being. Just shutting it all down immediately without notice leaves a bad taste in my mouth, and I will not be among the people returning for their next relaunch. I am sure others feel the same way, and I don't think it is a wise decision to needlessly put off your early adopters if you're hoping for them to come back "next time".
I can see why the team got overwhelmed. I wouldn't want to have to deal with that.
