@me PIA does not meet two of our criteria: It has not been independently audited, and it's a US company.

The US has good consumer protection laws, and PIA has held up their claims in court in the past, but being within the Five Eyes makes it far likelier your data will be caught up in an NSA surveillance dragnet. For PTIO users we decided that was an important criteria, but other than that PIA seems to be relatively better than lots of contenders, just not our recommendations, IMHO.
