Neat, now I know what everyone using my vpn provider has downloaded! I will happily recommend that everyone buy a router that can be flashed and pipe all your traffic through a VPN. It doesn't give you perfect security, but it defeats a lot of attempts to deanonimize like this.
Even if you do everything right all your traffic goes through VPN...
This create a case where the “bad thing” you do woth the PC, is also on the same address as all your “good things”.
Let’s say with Google, your thermostat, your Wi-Fi enabled coffee maker, your game console, your phone, every website you connect to with any other device that runs through that router/VPN - they all know your VPN IP at that time and your account info at that time.
Let’s say your WiFi refrigerator mfg sells IP and account detail information as a service to a data mining company - as I’m certain some do - in order to “get around” your home VPN, someone might need relatively cheap access to this data.
Putting everything on a VPN gives a lot of devices and accounts to tattle on you.
A VPN for the PC alone might be a decent idea if you are downloading things on the PC.
