The issue is wealth imbalance and the fact that one man controls an insane amount of power. Also voluntary trades are always beneficial on paper but not so much in real life. heres a good book that can explain it better than i can (yes ik the irony of using amazon for this but still)
First things first, any VPN that pays YouTubers to advertise them prooobably isn't that trustworthy. ProtonVPN seems to be the most decent one IMO (and I'm not being paid to tell you that) but only because of their threat model and lack of advertising everywhere.
Really, you don't need a VPN. The whole "YOU NEED A VPN OR EVERYONE CAN SPY ON YOU ABOUT EVERYTHING" is only true if the website you're on doesn't use HTTPS, and you live in a country that heavily censors the internet.
If you do, well that really sucks.
