The point is not to make a choice but to be informed about how the industry is somehow tied together in interesting ways. I would also add that many of these VPN services turn your machine into a drone where you knowingly or unknowingly enter into a contract so that they can sell your bandwidth to paying customers to provide them with randomized IP pools so that they can scrape amazon and alibaba.
Better yet, use IKEv2, not openvpn. Windows, MacOS and iOS has native IKEv2 clients. And most probably in Linux too :) Just make and install VPN profile as yourvpn.mobileconfig text file.
That is interesting, but openvpn also has clients for android, macos, ios and windows as well as linux (gnome nmcli has it baked in, you can just import an ovpn file)
It's not illegal, it's against their TOS, bug difference. In any case, if there's money to be made, you'll find even more reputable entities will operate at the margins of ethics and legality. In any case, probably more cost effective to come up with a technical solution rather than suing every pop up scraper of Amazon. Or just sue the VPN provider itself?
Not sure about VPNs, but data centers usually harbor their own RBL services to blackmail you to stop doing whatever you are doing as soon as you put their network under stress or continually visit a certain domain/ip range (or get hacked and be used as a drone to DDOS some website)
