The usual answer is "the self-hosted options are worse to use and make people hate them". Mattermost is a prime example, it's really clunky and uncomfortable to use. I like Rocket Chat and have hosted an instance of it myself, but it's shot through with inconsistencies and annoyances that Slack just doesn't have.

The notion that self-hosted is more secure is curious, though. Slack's security team is almost certainly better than yours, for most--not all, but most--values of "yours". You might be the rare exception (I'm certainly not, and I build reasonably secure systems by habit, if only because I don't have the time or money to focus solely on a chat service), but I doubt it.

Hi Eropple, Mattermost team here. Sorry to hear your Mattermost experience wasn't smooth. Could you share an example or two of what we can improve? We ship new releases every month on the 16th. If there's something you feel should be corrected I would love to see it addressed. There's over 500 contributors on the project and thousands of companies that deploy it.

In terms of security, I would propose that professionals dealing with sensitive data are often more comfortable with a self-hosted solution. As an example, former members of the CIA, FBI and NSA have used Mattermost on national television in the US: https://about.mattermost.com/open-source-mattermost-software...

I'd be a lot more inclined to spend time responding to you, because I certainly have a list of beefs with the software, if you didn't immediately launch into pimping your stuff and trying to sneak in how wrong I am. That's "I choose to exhibit the social acuity of a space alien" behavior.
