I've been forced to use Slack for the past 5 or 6 years in my professional life and I despise it. It gives me absolutely no ability to customize or automate my workflow without my employer giving me the keys to the kingdom, which they rightly won't do. Slack's service is where the value is. The client is only a means to an end. And yet they guard it with such zeal, threatening those who develop augments or alternatives.

I have the skills. Just let me automate my own machine without making me have to fight you tooth and nail!
