Why would they even have to comply with BS EU laws if they're based in the US? It's like that old Monty Python sketch... "To fix Britain, let's tax all Chinese people living in China."

They don't even get revenue from ads, almost all of it is from donations and they accept BTC, so there is nothing the EU can do.

And if the EU orders ISPs to block the domain, there are VPNs and Signal could build in Tor support.
