I've worked for a few small startups and smaller IT teams in larger corps, so the option of "call your ops team" isn't really feasible, so in that sense Slack wins because it's easy enough for the business owners to set it up, send out the email invites, and feel that it's relatively secure. I think Matrix is an all around better option, but just believe that they are missing why small companies or strapped teams pick Slack in the first place.
