Uhh. What
I never ever would have given Heroku a try if it hadn't been a free place to spin up toy projects. I definitely did not have an "account executive".
There's some vague language in here about people abusing the free plans for malicious purposes, but other, much smaller providers don't seem to have that problem. It sounds to me like they've just decided to abdicate the low-end market and go full enterprise, and are trying to hand-wave a justification.
RIP Heroku
