Don't know why you think you know where I live. And you seem to have completely missed the disclaimer where I said "Obviously if you have a data cap then that’s a different story."

And just FYI, for areas with a decent internet network, whether in the city or not, your data use doesn't impact your neighbors' bandwidth in any meaningful way, assuming your ISP isn't massively over-subscribed. I mean all ISPs are oversubscribed to some extent, but then most people aren't download 24/7, so they typically size the 'pipe' to accommodate peak combined usage.

I'm perfectly well aware that if your local ISP's network is dogshit then this might be more of an issue. That's why they typically have data caps in those areas to discourage bandwidth usage. If you don't have a bandwidth cap then it's really the responsibility of your ISP to provide enough bandwidth for everyone to enjoy. You want to go around ranting at people for watching HD movies, go right ahead, see what happens. Try ranting at your ISP - it might be more effective.
