When they first announced this change I thought it was simply an update to their license registration database that will render all unregistered licenses as dead. Now, with what is being reported by resellers, there seem to be two paths they might be taking. (A) Only sell perpetual licenses directly and not through resellers. (B) Go subscription only.
If they do subscription only going forward, but keep WUP around and grandfather in existing perpetual licenses (both of which would be the customer-friendly thing to do ... this is Waves though), one unintended consequence is the value of a Waves account takeover would be likely to appreciate, unless they get really hard assed about policing those.
