Folks, this should inspire you to start self-hosting a federated, decentralized chat server with freely available source code by yourself or with a small community. Governments can coerce these big, usually-corpo centralized servers to give up data but good luck if there are hundreds of thousands (of millions?) of small servers with 1–10 users on it & clients not controlled by a single entity for distribution (easier now that y’all coerced Mommy Apple to let you sideload applications & use alternative package managers).
