Well, you've shifted it for sure, but I still think this can improve the situation:
- It's residential ISPs that are unreasonably tracking metadata, rather than infrastructure providers.
- Even if that no longer applies, it's possible to use a VPN in a friendlier jurisdiction.
- The details of what you are doing are more obfuscated. If you're sharing a VPN, that has obvious benefits. If you use an anonymous VPN, even better.
Ultimately there will always be some data about your internet use available to a determined adversary – it's ultimately just a side-effect of wanting to send data across a network. But I'm personally more interested in opting out of the dragnet-style metadata collection that's being played with in the UK, so keeping my traffic out of sight of my ISP is a benefit.
