Private Internet Access (PIA) is involved in the whole Freenode fiasco, and has Mark Karpelès (of Mt Gox fame) as their CTO of the parent company. They also run ads all over the internet. Everything pointing towards just caring about the profits.

Mullvad is a low-profile company based in Sweden (strong guarantees for privacy) where you can even sign up by sending cash in an envelope. It doesn't get more anonymous than that.

On the technical side, I've been using Mullvad since probably 2012 or something like that, and lately just their Wireguard implementation. Always have had good performance and never received any complaints, even though I have used it for torrenting and bunch of grey-area stuff.

Edit: I see now the author has even highlighted PIA as their "top pick", which for me compromises the integrity of this list. PIA most likely paid the author to add that for them.
