"If you check the servers, they use many of the same 3rd party providers. Mullvad, IVPN, and TorGuard all use M247 for New York and Los Angeles. So if you connected to LA Mullvad, then switch to LA IVPN, thinking you’re getting a “new identity” you’re not. It’s NSA passive surveillance on the size of data packets going in and out of places like M247 that reveal you, and NOT Mullvad backstabbing you."

Wouldn't this actually be positive in terms of privacy by hiding in a larger dataset? While just mullvad traffic can be small for a specific server, if its mixed with IVPN etc. users, that's a larger dataset on the network layer. I would still rather they own their own servers but short of that, it's probably better they use the same provider.
