I'll revert this infraction if you give proof that you're a licensed lawyer specializing in intellectual property and copyright law. If you're not, you should probably try to avoid making statements from authority on such matters.
Pulling the plug on add-ons is NOT the same thing as trying to restrict that which they cannot. Add-on authors own copyright on their work, therefore they can do whatever they want with it, ads or donation messages included. Not that I want paid addons or ads in my game, but it's something add-on authors can choose to do. You're fooling yourself if you think Blizzard can enforce this.
It doesn't really matter that Blizzard provides the API for authors to hook into. They wanted to do that, because they want add-ons. Same as any operating system or software or anything else that opens up their API to external add-ons/plug-ins/programs.
