As others have said, Slack is fine for businesses that can afford its extra features, and it's "good enough" for a small business with less need for search history and more of a "run anywhere" instant communication platform.

But I agree with the sentiment that it's not a good fit for open source projects. For that, an open source Slack-like tool like Mattermost or similar would be a better idea.

In my mind, Mozilla is an open source company though. One of the preeminent open source companies. Didn't they create Bugzilla?

It would be really strange to me if they used a closed source community messaging platform.

> Slack is trash and hostile to users

It seems better than Skype and Hipchat and whatever Google's latest chat app.

But how about Matrix, Rocket.Chat, Mattermost, IRC, and other open source chat servers?

Mattermost is a terrible example of open source. It is just cheap rip-off of Slack and every pixel say that.

That’s the only one I mentioned that I haven’t used. I just figured it’s open source, so it’s more suitable than Slack or Hipchat. Thanks for the feedback, won’t be going out of my way to try Mattermost.

I have not used them so I cannot comment on that.

+1 for Matrix. Awesome technology.

> It seems better than other trash messaging platforms.

I mean you're not wrong, but you're not setting the bar particularly high :).

I think we need to be explicit, Slack isn't always conducive to the needs of open communities. Some of its features are extremely friendly to users, like having the possibility of full message history retention and mobile apps. But the former does require you be paid, and the latter is also possible with other solutions.

And immensely better than Microsoft teams

Notably, pasting code into skype seems to be an emoji-filled land of adventure.

Although everything is better than Google Chat.

That's debatable. I can't stand hipchat but at least it doesn't fall over loading gifs.

Is it really debatable when Atlassian gave up on hitchat.

It could be worse and they'd switch to Discord.
