I see. Well, as you surmised in the previous comment, control over data requires personal attention, and the only way to give it is to host one’s own VPN on a VPS. I even came across a few VPSes who accept Monero.
Another commenter mentioned that hosting a VPN in an address space full of servers can make one stand out, which is obviously not in my interest. I am still trying to think of a way to balance privacy and obfuscation since this point was mentioned.
It’s not about the websites leaking data, it’s about being as anonymous as possible. And my search makes me more disheartened as time goes on, as the systems we have essentially break any semblance of privacy. The only private life seems to be offline, and even that is not warranted. It is very difficult to live without the internet though
