To everyone, I'd like to remind that AirVPN did lose one or two servers because of government intervention in the past. One very delicate example was Ukraine somewhere in 2015 during a politically even more delicate time: Euromaidan. The server was seized, but no one lost his or her head for it; AirVPN held its word back then.
I can also vouch for this a bit – I read some of the code of the AirVPN library and Eddie for PC, even if, in case of Eddie, it's C# which I don't usually work with. Nothing suspicious was seen so far, but truth be told, I was not reading it like a novel.
About the whole 5-eyes and 14-eyes thing: I think it's marketing slang. Somehow people get the notion that not being in 14-eyes is a plus while the horrible truth can be as simple as the company deliberately moving their HQ outside 14-eyes while the overlords are still chinese or NSA agents or something.
