The funny thing is that the reaction of these platforms when someone advocates for communications elsewhere is to ban those people rather than try to improve their system so that people don't want to leave (reddit is hardly the only platform to act this way). Personally, I'd rather try to build something so excellent that if someone proposes an alternative, most people wouldn't want to leave because I am meeting their needs so well. If the platform is so sclerotic that it can't be meaningfully improved and people are clamoring to leave, there is little they can do prevent an inevitable mass exodus anyway.
