This depends on your treat model. If what you worry about is massive collection of Linux ISOs that you download and distribute over P2P then probably shady VPN ISP is what you need.

I'm a normal person who watches sports streams and maybe 2 years ago I downloaded a torrent of some art movie. My ISP is Comcast. How does your advice apply to me?

Exactly. Most ISP are subject to local laws at least; where a lot of these ISP are overseas in shady jurisdictions.
