I would assume most free vpns will be blocked period (either intentionally or for triggering the adblock ban).
And if you are going to pay for a VPN to watch youtube… youtube premium actually IS a really good deal for the creators. The specifics are obviously unknown, but most creators have come out that it is incredibly favorable and a lot better than what they get for ad revenue. And that automatically goes to whoever you watch rather than forcing you to decide if you REALLY need to throw a buck or two at the lady who actually showed how to install a sharkbite rather than glossing over it.
Aside from that: Like with anything, just question how much it would impact you to lose a google account… or all your google accounts. If you can eat that loss, yolo. If not, maybe avoid getting into an arms race with John Google.
