Yep, time to self host one of the awesome self hosting list's chat options. This will teach independence too. I have a ready ansible deployment for zulip using docker in my repos [1], publicly available. All that's needed is a server, setting some variables in ansible, deploying that thing, and adding backups. It will cost significantly less than any slack subscription and will not cost per user.
It's really easy to join! There are lots of cool programs currently running. Maybe wait until next week so the migration is done, but do check our website: https://hackclub.com (we have/had 100k people in the Slack)

So if you use an open standard, but not self hosted, and your provider tells you "pay 250k or lose all your data in 2 days", I'd say are not necessarily in a better position than they are now.
It's not impossible to migrate off of slack, but migrations take time.
that's a perfect teaching occasion, then!
Kids: don't use proprietary services just because they are trendy. Prefer always open standards!
