Not an issue when you run your own VPN with a cheap VPS - meaning the data is exiting in a datacenter in a location of your choice. While they or their upstream providers will certainly have some 'lawful interception' capability they are usually not interested in analyzing / selling the data on their wires as the consumer-facing ISPs.

Can you provide more background on your blanket statement?

There are good and bad VPNs but ISPs are much larger corporations with direct ties to governments. I fail to see how a good VPN is worse than ISP + Governments.

Depends on where the VPN connects to.

I control the other end of the VPN, I'm not using a public VPN service. All I care about is routing around my ISP. (Which is Comcast - whom I do not trust.)
