Commercial VPN services certainly have some valid use cases but for the vast majority of the population they effectively do nothing or worse.
If there’s any benefit to their proliferation it’s in the security service case. Now that all of your non-technical friends have signed up for ExpressVPN because they heard about it on a podcast there’s just that much more data to sift through. Not that security services can’t handle vast amounts of data… I’m just certain that from a classification standpoint intercepted data coming out of a VPN (and certainly Tor exit) is likely classified higher for analysis, potential manual review, etc. Much bigger haystack in the VPN/Tor case.
