Who does this? Edited a page and unable to save changes due to a licensing dialog that pops up. That is the true cost of licensed software and the #1 reason to use something else. Turns out nobody can save edits now. Sensible behavior would be to a) bill for overage, b) allow edits but send a notification to customer about overage.
Are they worried we will "steal" usage if somebody saves an edit after license count is exceeded? I would be more worried about existing customers sharing this experience with other customers.
