I don't know, the criticism in the list is certainly irrelevant, but as far as I can see PIA is a US company and I believe it is kind of absurd to nowadays trust any US or UK company about privacy-related matters. The UK has become one of the worst countries in the world regarding privacy due to the Investigatory Powers Act, but the US also doesn't have a good reputation in this regard.

A simple Google search also reveals various user complaints that PIA apparently uses a Ruby (!) script to constantly write an extensive local log of all web activities, and the option is switched on by default. That's not inspiring my confidence. Their pricing is great, though.

The problem I have with VPNs in general is that quite a sizable number of them look as if they had been set up by dubious entities solely to collect data on their customers. Especially the ones with competitive pricing.

I would rather trust some of the more expensive ones from e.g. Sweden.
