As I said before here recently; I am replacing all my tooling by stuff I built and that includes chat. I own my company so my colleagues can leave or use it too (they help me build so yes, they will use) and family will come on board if they have a side access to people who won't, which we do: we integrate other chats and for those we losen the rules. I have no interest, when I die in 40 years, to depend on even one line of software not inspected by me.
