Great product, but trust is everything when it comes to such a core part of a company. They fucked up, real bad.
I'll use this while we transition away, unless there is a community fork which is sustainable and is firewalled from the morons at mattermost org who fouled this all up
Haven't there been CVEs in the product since they forked it in 2024?

There's also Mattermost-LDAP, though it doesn't look like there's a support contract for when compliance is important: https://github.com/Crivaledaz/Mattermost-LDAP
IIRC there are also 3rd party SSO/LDAP/AD adapters for GitLab?
