I'm very disappointed with the level of comments here - the emotional attachment to Slack is just not neccessary; same for the ad hominem comments. For sure they have a great tool that I love and use but they have been slow to act upon the fact that many communities are using their free option with huge numbers. Rightly or wrongly. Slack just simply need to decide whether they are supporting this model or are happy to hand it over to Gitter to deal with. I suspect Gitter will be more than happy. Personally I think they could offer a fixed fee for public rooms. But hey that's up to them, it's their business model to decide. I think the problem is just the lack of clarity about how they are going to manage what they definitely know is going on (I have asked).
