Well, you can always use Riot with a Matrix server in whatever country you like (or run by a company HQ'd in whatever country). And the code is all open, so you can always check for backdoors or build your own copy. For folks worried about the security of the default hosted service for Riot I guess we could set up a canary or something but I really hope we won't get to that :(

(Also, in practice Riot is half UK and half French - although France has its own fair share of crypto confusion).
