At this point, consumers should know that "for life price" is a scam to get gullible customers through the door and gain market share or collect user data. Just like with a Ponzi scheme, consumers should realize by now why such pricing is not sustainable long term due to inflation and other costs, and either the business will crash or they'll have to inevitably backtrack on that promise and raise prices to stay afloat. You can't have your cake and eat it too.
No excusing Google of this scam, but they only did what every other company with these kind of hollow promises did.
I vividly remember Cerberus on Android was selling one time licenses for life, only for them to backtrack on that years later and switch everyone to their subscription instead, publishing a letter along the lines of "sorry, we know it sucks, but the lifetime licenses we sold you are unsustainable financially for us, so we'll switch you to subscription UwU."
Same with Google's unlimited Photo storage.
I'm sure when they migrated users to YouTube Music they got rid of the special deal.
So you know, the standard Google experience.
