You're popular because you're free. You've transferred that logistical problem to another team who happened to offer a free plan without your use case in mind. You've made your problems the engineering problems of another team, except in the other team's case, they're accountable to investors and a bottom line.

While I agree that they had totally unrealistic expectations (and you forgot to highlight the 5 service integrations bit that he also complained about later), slack does also advertise "no limit on users" when they do in fact have a limit.

"Small teams" and "no limit on users" aren't really compatible, and it's pretty normal for people to just read the bit they like and ignore the rest.

Slack should probably just put a 100 (or even 500) user limit on the free plan to discourage people from signing up with such unrealistic expectations.
