It doesn't matter when Apple made the statement regarding tripling ad revenues when they had already been implementing ads in the OS for at least a couple years now. There's no change in Apple's behavior here except to expand upon what they were already doing long before any new laws were passed. If Apple had never put ads in the OS before you might have even a crumb of an argument. The fact is Wall Street expects never ending growth and this is simply Cook's attempt at continuing that expected growth for AAPL.
Agree. Apple implemented search advertising in the App Store nearly six years ago. If they were willing to do it then and it eventually proved to be a decent revenue generator (which it did), it's only logical that they would look to expand it at some point and find ways to increase ad revenue even more. This is not something that was only thought of recently or is in response to EU regulations.
