Recommended by whom? I'm just saying your advice is terrible in general and takes no regard to how easy and powerful fingerprinting is nowadays, in google's perspective the only difference to using that VPN if you're "just" running chrome is that it also knows when you use a VPN, in other words, just giving one more data point. Also the average user is likely to install some nordvpn app if following your advice, which is a security nightmare, remember that company sells residential proxies.

Also IIRC for youtube, alternative frontends don't tend to rely on someone else's endpoints.
