Well, this is one hell of a Gotcha! for everyone who is using in-app purchasing. Wasn't it the responsibility of Apple, Google, MS, to inform developers of this? Hm, I wonder if HP has a license for webOS.
And does this apply to desktop in-app purchases? What about in-app web app purchases? Does Facebook and its devs need a license?
Hmmm... could that have been a notice error in their glee to target everyone? If it applies, this is a damn bigger issue than everybody yet understands!
