Depends on what you want to achieve - but yeah, rolling your own is great too - but I’d opt for WireGuard over OpenVPN.
WireGuard is a peer-to-peer tunnel protocol/platform. It is not a VPN. Yes, they are different things.
It's the difference between, say, a /24 or /64 and L3 vs. a /31 or /127 on L2.
Or an e.g. switch vs a crossover cable on L1, and so forth.
But if you want to bypass geo-restrictions or get a little more privacy by “blending in with the crowd”, it might be worth it to throw some money at a VPN service.
1.) Geo-restriction bypass is a never-ending game of cat-and-mouse, and only encourages unscrupulous business practices by media platforms, media producers, the collaboration they share, and their associated lobbyists.
2.) a.) Tor + (Tails OS|Qubes OS) plus browser fingerprint falsification is better for identity noising. Anonymity/privacy via a VPN provider is a lie, because
b.) Being centralized businesses and/or organizations, they are directly subject to warrants and other law enforcement interventions. All of them keep logs. Some of them lie and say they don't. That almost doesn't even matter, though, because
c.) They have complete ability to examine the entirety of your traffic. The VPN is only encrypted *from* you to *the VPN provider*, not *from* you to your destination. The only safe option there is strong *actual* E2EE between you and the end destination/service. Your VPN provider is just the same as your ISP with less government regulation, as far as privacy goes.
