And your "VPN in YouTube ads" surely does that
Yeah, that's the point. People have infinitely more choices for VPN providers than for ISPs. The VPN provider could be in another country. You can even run your own VPN on hosted infra.
This comes with its own risks and you lose some advantages of a commercial service, such as being "lost among the crowd" of other VPN users.
True. But we know very few people do that
And you are sure your connection to a VPN service won't get you flagged ?
Sure, you'll probably end up facilitating a few petabytes of copyright infringing torrent traffic every day, but you'll also have a direct connection to countless people who think they're totally anonymous.
This is the best part really. No three letter agency is going to spoil their honeypot in order to bust some kid for downloading movies and video games. They've got bigger fish to fry. The more successful they are at keeping their users safe from the copyright goons the more popular and "trustworthy" their little honeypot will seem. Your downloads will still probably earn you another black mark in your dossier, one more thing they could use against you if you ever became a problem for them, but still, free movies, music, and games! Might as well make oppression work for you.
Huge benefit in my opinion.
