Enshittification comes for open source:
Slack is kicking two large open source groups, Cloud Native Computing Foundation and Kubernetes, off of their donated enterprise tier, giving them one week notice to migrate multiple years of data to a new platform before it's all deleted: https://www.cncf.io/blog/2025/06/16/cncf-slack-workspace-changes-coming-on-friday-june-20/

Instead of learning from this experience and not trusting the good will of profit-motivated closed source companies, it looks like both projects will be moving to ... Discord. Because "people know it." Will we never learn?

(Dropped Cory because he's probably getting tons of spam from this. Sorry!)

CNCF Slack Workspace Changes Coming on Friday, June 20

The CNCF Slack workspace will be converted from an enterprise plan to a free plan on Friday, June 20, 2025. This will have implications for how Slack works for our community…

@huxley what are the open source alternative?
@jstockdi @huxley I use Discourse for my projects. It's more forum than chat, though it also has chat and PM features. But, it is easy to administer, has good moderation and anti spam tools, and is easily searchable without an account. I have literally no complaints and I always have complaints. Discourse is close to perfect, in my estimation. Can be self-hosted or they offer a hosted service for a reasonable cost. I self-host it, as I need custom plugins and WordPress auth integration.

@jstockdi
Also Mattermost and Zulip which look more similar.

I recently setup Discourse for teammates as well, because it has a forum part and a group chat part. However there is little engagement, which I think is due to: people are too shy to post on the forum, or maybe they think what they have to say is just unimportant. Chat would then be better suited for spontaneous interactions, but you don't get enough notifications from the Discourse chat to make people stick.

@swelljoe @huxley

I think the lack of a proper phone app also doesn't help hooking people.

@swelljoe how about your experience, did you get people easily involved?

@GullumLuvl Discourse works great on phones, just as a web app. I never thought to even look for a phone app. The chat apps are all JavaScript all the time, anyway, so I assumed their phone apps are just just web apps thinly wrapped into phone apps? I never think "I wish this website had an app for my phone", I just want the website to work well in phone browsers, but I may be unusual.
@swelljoe yeah the web app is great, but I wish I could have notifications from it, even with the tab in the background. Not sure if that's doable, I never tried as I usually avoid notifications πŸ˜
