1. Though people are being asked to purchase YT Music, they're being given their original, grandfathered price. They're not being asked to pay more (aside from the person who moved from AUD -> USD).

3. The modern public terms don't seem relevant here. YTM also doesn't have a $7.99/month plan, yet that's what's being offered to you. Is there any compelling evidence that accepting Google's purchase links means surrendering your lifetime price guarantee?
