I haven't seen them promoting that hard as you describe.

I wrote my comment of the pure satisfaction with their services and my use case. So stop being ignorant and be civilized and at least argument what you say. What happened to them month ago was an accident that could happen to many others, but the difference was that they were 100% open about it, with others you may won't even know shit is happening.

Nobody forces you to use anything.

Edit: And now you edit and delete 90% of comment, nice.

(My comment excludes the CI part)

I have. I've installed Gitlab and Mattermost on my own server. Gitlab is great but I found Slack was a better product (over Mattermost). Have you tried installing it?

I created a Gitlab account and was planning on using it over Github but their recent data loss scared me off. Is that unreasonable? It worries me just as much to see them buying a company a month after that. Is slowing down unreasonable?

I want to use Gitlab. I like their open approach, but if people just praise them without being objective about it it doesn't benefit any of us. I might just be a selfish and/or entitled user but you'll forgive me for wanting Gitlab to be good. Don't you?

No, please tell me how you installed a Slack server! (j/k, but it's also kind of the point: GitLab wins on-prem)

Mattermost team here, would welcome any feedback on how we could improve.

Here's a demo of Mattermost features vs Slack as FYI: https://www.youtube.com/watch?v=AKqHWqrAgpk

I had some confusion with the install. It seems the Docker install is favored, but not using a lot of Docker stuff I went with the gitlab-omnibus install on Ubuntu 16.10.

It worked but I didn't feel especially comfortable with it, there were a number of steps. That's vague enough be useless and it could have just been my own ignorance. What is the suggested install if that isn't too basic of a question?

I also had issues with it not liking users sending rather large files but I believe that's an odd use case.

I would use it again but the simplicity of Slack (no setup and no management) won out for now.

"What about Mattermost, how is this different?

Gitter was built to be used in the open. We’ve always seen Gitter as a network, or a place where people can come to connect to one another. Team collaboration, whilst possible, has never been a core aspect of the Gitter experience.

Mattermost is a powerful, integrated messaging product for team collaboration - we will continue to ship and recommend using Mattermost for internal team communication."

They surely have the best intentions. Hopefully one product doesn't take priority over the other and/or they can prevent cannibalization. There's definite overlap.
