No, but there is some cheeky stuff they can do (and while easily stoppable and preventable) can get most users unexpectedly.

HTTPS and a lock next to the URL does not make you safe and I have no idea on the where TC is, what his system is doing, what the laws and regulations of where they are, and there are some reasonably high profile example of this around the globe.

honestly it was more of a "fuck idk" kind of reply rather than realistically expecting an ISP to specifically target a single site while maintaining unethical and insecure practices that would lead to this happening. Its technically possible but if you told me it was I would think your wrong and that it was something far simpler that's been overlooked.
