Time from “Skype is dying” to “I have spun up self-hosted Mattermost for work” is like 3 hours.

One more reminder that Slack is a terrible choice for communities, and extorts even nonprofits. Even when it’s one teaching teens to code, for free.

Hack Club is moving to Mattermost. They really have no choice.

Just a poor taste how Slack demands $50K in a week, no real notice

I'm leading a Mattermost pilot for a big community that is moving off Slack. It was estimated that paying for Slack (necessary to keep messages longer than 90 days) would cost nearly $10,000 per month. I am hosting Mattermost on Reclaim Cloud for $0.59 per day. Open technology makes sense.

Proton has been building a lot more features that can help with that sort of thing, and it's turnkey. For more complex stuff, I know of some folks who use Mattermost.

Mattermost -- чмошні чєрві: вони монетизували свій продукт (аналог Slack), але зробили це через примус та дискомфорт.

Тепер існує обмеження на 10К повідомлень, а все що більше -- потребує грошей. Люди обурені <https://github.com/mattermost/mattermost/issues/34271>.

We're looking for someone to lend a hand with our wiki migration project: more coordination than code. If you're organized and want to make a real contribution to Rocky Linux, come find us on Mattermost.

Cool. That gives us plenty of time to adapt.

FUCK OFF.

This non-profit will also run a community #mattermost server, a #mastodon instance, and soon a #peertube instance. These are free and open source alternatives to those developed by our tech overlords.
