Opera had been acquired by a Chinese company and after that the browser went full on telemetry and IIRC same privacy policy works for their "VPN" too.

Opera just got bought out by some chinese company. It's for you to choose whether that is or is not a concern for you, but I personally am uncomfortable with such a company as my VPN, particularly I can add it to the server which I already keep for miscellaneous uses.

I was skeptical about Opera's VPN, but it does seem to work. Of course, I don't count on it not logging my real IP, but still, it's a useful free service.
