Jurisdictions is a tricky business as it completely depends upon where you are based yourself, and the degree to which you need to protect your browsing. But in short, yes. Where the servers are based has a bearing on the laws your traffic is exposed to. And if you’re in most of Europe, using a VPN from the US is probably not the best idea. However it also depends upon whether the VPN provider will legally challenge any government requests, or just happily hand over your traffic and information.
Knowing Peter (who runs iPredator) and his in-depth knowledge of jurisdictions, if you’re concerned about location, I’d stick with iPredator.
I’ve used Freedome, and while F-Secure is huge, they’re very security, privacy and free/open-focused, so I would trust them before I trust any random VPN brought up by a web search.
I primarily use Cloak to protect me on public WiFi networks, as it triggers automatically, and WiFi security is Cloak’s focus. I also use it to sometimes spoof geographical locations for debugging.
And thanks for the long post, these are very important nuances!
