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)
