They're now a defense contractor, the copy on their website sounds like military cosplaying.... Probably chasing the stupid profits of Anduril and Palantir, and doing the old open source rugpull in the process.

Zulip (for Slack) and Wekan (for Trello) are good replacements, save yourself the ethical and technical worries.
