Trapping you between your entry into a VPN's network and your exit out out the other in the internet as a whole is child's play compared to doing it around your use of TOR. And everyone should already be aware the TLA's already have done that repeatedly. Signal's Intelligence has changed all that much since Shannon was around.
I use a VPN here for two reasons. (1) Comcast. (2) Should I be accused of something untoward, it will help the people around me deal with it better if the untoward traffic is all identifiably mine. Given the feds scorched earth tactics, that's a consideration. Take my gear, leave theirs alone. I wish them well, going through my stuff will take them the better part of a decade. [Digital Packrat]
