AI Pro Plan users - Have you received an unexpected YouTube Premium subscription?

I started watching something a few hours ago and didn’t see the ‘Premium’ label, but now I’ve clicked on it and see that I have it. Could this be linked to the recent changes to the AI plans? There’s no mention anywhere in the email that I’ve purchased a subscription, not even in the email I received from Google regarding the changes to Antigravity.

Yes. Same time frame.
