I don't know anything about Plex, but torrenting is pretty effortless compared to figuring out which streaming service what you want to watch is on, figuring out how to get that, evaluating other content it has trying to justify the price, figuring out how to get it to your tv, and figuring out how to use it. The only thing I've seen that confuses people about torrenting is having to open a port.
I think the thing that limits torrenting is the ISP emails, not any of this "nobody cares about your nerd stuff" know-nothing pseudo folk wisdom. People figure it out in five minutes, it looks too easy so it feels criminal, then they get an email from their ISP, so they retreat back to the difficult stuff out of paranoia because they vaguely remember stories about people getting in absurdly disproportionate trouble for it.
For your conspiracy to be valid, I'd have to see significant evidence that internet costs have gone up in the US. Mine have gone down. Evidence that it's cheaper in other parts of the world is utterly irrelevant.
