Briar can be distributed from device to device via a direct download and works without relying on a central server. You can even chat without access to the internet via bluetooth or external storage. I don’t think getting rid of Briar is going to work… ;) What I’m trying to say is that Briar was also made with laws like these in mind, and it will be able to continue existing even if Briar would be forced to somehow disable downloads from the eu.
