PIA was sold to Kape Technologies a few years back and they have somewhat questionable history and that made me switch to Mullvad. Not because I thought it's better VPN per-se, but because I wanted away from PIA and Mullvad seemed popular.

The issue is who he sold it to -- the notorious creator of some pernicious data-huffing ad-ware, Crossrider. The UK-based company was cofounded by an ex-Israeli surveillance agent and a billionaire previously convicted of insider trading who was later named in the Panama Papers. It produced software which previously allowed third-party developers to hijack users' browsers via malware injection, redirect traffic to advertisers and slurp up private data.
