That's not how the market works. Every large phone manufacturer already had big investments in would-be iOS competitors, such as Symbian or Bada or Maemo/MeeGo or WinMo. These companies are also big enough to not see the impeding danger of their conservative investments until it is too late.
The iPhone wasn't considered a real threat (remember how Ballmer laughed at the iPhone?). If the requirements for Android would have been restrictive enough for manufacturers to realize that Android is a great deal, I don't think it would have caught on so well and Microsoft could have eaten their launch, since they are better at selling operating systems.
