PIA gets a lot of recommendations but no one ever mentions that a great number of sites prevent you from using them from the PIA addresses. I've had a lot of trouble with financial and e-commerce sites in particular (which are also the situations I really care about using a VPN).
I think it might be that PIA is frequently used for DDOS and abuse since it's so inexpensive.
Just something I wish I had known before signing up.
As a developer, I would actually have to read up to know exactly what a VPN is and what I can do with it. I have a rough idea, but as it has never been something I have worked with, I have little knowledge of them. Now how would you expect the general public to manage, without someone giving them a decent explanation of them.
I don't think ease is a barrier anymore. I think it's just lack of education about how necessary these measures are.
