It would be easier to leave if you started by using a platform that made that seamless. Freenode gets bought & communities say to point your bouncers/clients to Libera.chat or OFTC. If you were on XMPP on a decentralized account, your account stays, but now there’s a new MUC to join. With Discord, if Discord goes down, so does the client & the whole server… folks need to relearn a bunch of stuff & it’s not a clean break.

This is also inevitable as we are talking about a US-based, VC-funded service & we have the entire track record of these types of services declining. Why not start with something that’s more likely to not suck in 5 or 10 years even if it doesn’t have all the same features so long as you can still chat in realtime.
