Does it actually? (Genuine question.) The article doesn't get into specifics about how the block is implemented, but I wouldn't be surprised if there is some non-trivial way around it.

Or, conversely, I'm unsure if other decentralized platforms would be unable to implement a similar block.

The client checks https://bsky.app/ipcc locally on startup, and if the json object it gets contains "isAgeBlockedGeo : true" it displays the block message.

ublock origin filters can replace the contents of any page using regex.

TLDR it's a single geoloc RPC call clientside. you can just tag it with an adblock filter to kill it. Or use any third party client (my comment to OP has a bunch of them listed).

Interesting though: I wonder how long til site host lists and ad filters start shipping anti-censorship lists and features. We know some DNS provider is already doing it. (I forgot which one)
