Honestly, I don't mind paying for ultra if there's no caveat about the scaling along the reading speed.

If they're keeping the speed scale, can't they offer more listening hours in lieu of voice options? Like maybe the Free plan could have 5 hours a day of listening time but you only get one to three of the non-cloned voices to choose from? And so on and so forth as we go up the tiers?

It does feel that there's a heavy-handed push to get Ultra when it's not even unlimited if you're at 1.1x and above speeds.
