I've been running RPI-based torrent client 24/7 in several countries and never experienced that. Eats a few TBs per month, not the full line, but pretty decent amount. I guess it really depends on the country.

I’ve used Spectrum and their predecessors since the 90s. Never ran into this, although the upstream speeds are ridiculously slow, and they used to force Netflix traffic to an undersized peer circuit.

I'm unsure if you're sarcastic or not, never have I've used a ISP that would throttle you, for any reason, this is unheard of in the countries I've lived, and I'm not sure many people would even subscribe to something like that, that sounds very reverse to how a typical at-home broadband connection works.

Of course, in countries where the internet isn't so developed as in other parts of the world, this might make sense, but modern countries don't tend to do that, at least in my experience.
