None of my business, really, but as a member of the community who has used AirVPN daily for years and who has family and friends who have as well, and who is an engineer with decades of experience solving technical problems, I'm just going to interject that I am also offended by the OP's attitude that if something is wrong, surely it must be because someone is trying to cheat him.
Super poor vpn performance across many of a providers' servers is actually not indicative of a "bad vpn" (go stand in the corner!), but the technical settings in the software that will work for your situation can depend on many things, even the particulars of your ISP's service. Set the MTU too high for a particular ISP's network, for example, and you can bring any VPN system to its knees, not because the VPN server is slow — it isn't — but because the network between you and that server is not getting packets to the server efficiently. In that situation it's like it can't run or even walk because it's tripping over its own feet with every step. Is that the fault of the destination?
Networks are complicated. It's the reality and a lot of crazy things can bog them down. Air has a really fast VPN system, and they have the best technical support I have ever seen. Work with them on sorting out what's going wrong in your particular situation and killing most of your speed, and do it without the insults. This is almost certainly something that can be cured with an easy adjustment at your end, once the problem is identified.
