This is the thing I don’t mind VPN companies advertising about, because yeah, they can work to get around region restrictions, and that’s a totally valid use for them that some people will appreciate. If you have a specific use case like this, by all means pay for a VPN… But if you’re just using it as a magic internet condom… I don’t think it’s worth your money.
In general the claims about security at a coffee shop or whatever are kind of bunk, and any privacy benefits are kind of overstated (especially if you don’t think you have a reason to trust the VPN provider more than your ISP). There isn’t a complete lack of truth to these claims, but I don’t think they’re true in a way that’s meaningful to the average person who isn’t tech savvy, and I think there’s often a lack of transparency about certain aspects such as the fact that technically the VPN provider can log everything anybody else would, and you have no way of knowing.
