Yeah, my VPN provider could be lying to me and logging a whole bunch of extra data under the table. But I know my ISP is logging that data. I have every reason to trust a paid VPN provider more than my ISP because my VPN provider is basing their business model on me trusting them, not on being a monopoly.
Not to mention that VPNs also help at least a bit with anonymizing IP addresses. The trust model I have with directly exposing my IP to a website is "I hope nobody I visit on the Internet is logging this."
If I'm wrong and my VPN is logging everything, I'll still be in a better position than I was with my ISP, because at least I won't be broadcasting my current physical location to every single website I visit.
A lot of people really do distrust their ISP enough that even with knowledge that you're shifting the responsibility to the VPN provider they still trust a random VPN more than their ISP.
Would I trust some random unknown VPN provider more than Comcast? Maybe.
I follow the same logic by setting up my own VPS in a rented $big_provider VPN. VPS companies are succulent targets that surely attract many eyes, whereas I doubt any non-state actor has the capacity of capturing and filtering the traffic of the millions of random VPNs that $big_provider has.
If in the Netherlands: probably Turkey. If anywhere else: probably the Netherlands.
Although it is hard to think about a scenario in which the only available choice is between the Netherlands and Turkey.
The idea is hedging against the closest guy with a stick.
Therefore, going from three to eight ISPs is arguably worse as your exposed to nearly 3x the risk of exposure.
