I've never understood why a part of our community goes with this walled garden to host their chat. We're literally an open data project

Edit: fwiw, I know that moving communities is extremely hard, not to say impossible to achieve completely intact, but those who care could choose to join two chat systems. Eventually, the one people gravitate towards will win. E.g. I'm still in the Telegram chats and use those on occasion (also because, as a moderator, I get regular pings), but primarily share content on Signal or Matrix
