They offer a thing they’re calling an “opt-out.”

The opt-out (a) is only available to companies who are slack customers, not end users, and (b) doesn’t actually opt-out.

When a company account holder tries to opt-out, Slack says their data will still be used to train LLMs, but the results won’t be shared with other companies.

LOL no. That’s not an opt-out. The way to opt-out is to stop using Slack.

    For matrix specifically, I recommend fluffy chat on mobile and cinny for web/desktop. Most notably, they both support the not-yet-official spec on custom emojis and stickers, which I think is important for any slack-like.

    For the server (since you want to self host), you’d probably want to do Synapse - it supports not being federated as well as SSO. Also it wasn’t mentioned by mp3, but xmpp is another protocol that’s used by many large companies for internal chat systems as well.
