Excuse me for my lack of understanding, but why are there so many people looking to hide their traffic from their ISP with a VPN? Isn’t HTTPS enough? Are you afraid of ISPs resorting to DPI or MiM to spy on their users? Is customer protection so weak in the US that ISPs are free to spy on their customers using aforementioned techniques?
Edit: I just realized that I left out people leaving under authoritarian regimes, for whom VPNs are unfortunately required to evade their government.
