> I would fully understand that I am required to upgrade, but why not sending me an email before shutting down my business completely? I even asked about such scenario on zoom meeting I had with their Sales and they said it will never happen
They've done this to me, too—I read the TOS and tech docs and plan details and ignored them, because according to their own stuff, they were wrong, and "first-tier sales guy said it" isn't a helpful recourse if you get told to leave (so, migration costs) or pay $$$$ because you're violating their documented permitted usage.
Hilariously, they also seemed really confused when I brought up a gaming use-case that they had an entire sales landing page for.
(Nb I actually like, use, and would recommend CloudFlare for some workloads and use-cases)
