And I require more. Slack (for business), Hangouts (also for business and I need multiple user conversations enabled, Hangish does this on Sailfish), and JIRA/Trello (also for business) for instance. I could list out more, but I'm moving one organization away from Yammer and Skype for Business into Slack to avoid being in Microsoft's lap. Our needs differ. Why should you dictate what I have access to when your needs are far more limited/different than my own? That's the issue. There's nothing "open" about these kinds of talk. I hear "Well it works for me" far too often when honestly, a lot of you people would be happy with Lynx, VI and a terminal. If that was only option that could be supported, I don't want it.
