FWIW I know of a startup whose video sharing app was used to reshare a pay per view football match and they incurred a $30k bandwidth bill that AWS did not cancel. That killed the startup. It was largely their own fault for not securing the platform well enough, or moderating popular streams, but being able to cap their AWS bill would have kept them in business..
I am not going to risk runaway costs in hope that Amazon "might" cancel it.
Though, apparently population both caring about it and avoiding Amazon as result would pay less than cost of implementing it and not refunded income from catastrophic runaways.
The "might" in your post is doing a lot of work.
