As much as you're trying to help, the truth is, small projects don't have the resources to do stuff like this. Now they have to devote time (probably someone's limited after work time) to bringing you onboard, getting you setup, etc. Then, you set everything up and let's say you disappear. Now they have this custom setup that only one person knows how to operate. At the end of the day, Slack works. They're already using it. No one has to get trained on new software. You don't need new accounts and passwords and admins and teams. The list goes on. This is a big issue with small projects - everyone wants to join and change some thing that's not part of the core mission.
