There is nothing legally stopping you from doing the same thing for iOS and you can become an iOS developer much cheaper than a Gabe developer.

Legally, yes, you also have the right to do this in iOS.

Sometimes it doesn't matter what your rights are, if a company is willing to spend a bunch of money trying to submit illegal lawsuits to bankrupt you.
