In fairness isn't that a result of your relationship with your isp? If you remain because of price or no other services available why wouldn't you use a vpn knowing your isp is a hostile actor and probably trying to deeply inspect packets, etc?

You just shift the trust around. Now I have to trust the hoster, e.g. OVH instead of my local ISP. Really the best thing you can do is end-to-end encryption, don't send plaintext over the internet.
