lol, say someone publishes an E2E distributed extension to an existing chat protocol.

Are you going to arrest someone for writing code? Are you going to arrest people who use private communications? Sounds like a legislator carve out hot and ready to happen.

I get the point, ban E2E, OK sure, but what if some software is designed in such a way that the company doesn't provide it, but it just happens to be compatible with the protocol extension? Are you going to arrest the authors if they don't explicitly ban it?

Yeah, right.
