This is exactly my rationale. The fact that you have to explain that the company that bought you is
not shady is writing on the wall, even if you have a good explanation. For the record, I think the explanation is pretty decent. But PIA is a commodity product from a technical perspective. It's the trust and reputation that's not the commodity, and being bought by a shady company (
even if it's "formerly shady") you discard this right away.
I bought PIA because it had stellar reputation back in 2015 or so. Now it went from stellar reputation to "just another VPN provider". Mullvad appears to be prime candidate now, they're not based in the US if that means something to you, and they even have Wireguard to play with. Let's go.
