Yes, relative to Pro the new tier isn't as valuable, but it could still be more valuable relative to the old tier for the same price.
Yeah, I feel like I'm taking crazy pills.

Usage limit is - limiting. I may not notice the increased value of a more advanced model, but I will notice when I can't even use the service.
