The knee jerk comment is yours. 'Bye Bye Mailinator' is too short to convey anything useful other than the general case, that you believe that you or those that use Apple will defect from Mailinator in droves. The typical use case for Mailinator and the overlap between the Apple eco-system as well as the fact that they specialize in this and that for Apple it is 'just another feature' makes me question whether or not you have thought through the ambiguity in your comment, by taking the most probably meaning and responding to that you have a chance to clarify your position.
