What Alan did was inappropriate.
And to interpret news items about Apple as being negative is blowing things out of proportion. Most of it is FUD thrown around by competitors or their fans.
Some may decide the iPad isn't for them because it doesn't run traditional OS X, but it's a new class of product that by design needed an incompatible CPU. It's better that it do something different well, than act as a marginal chopped down laptop.
Judge things AFTER they ship. Apple does listen to customers. (some may remember changes to the OS X Finder in its early days due to customer feedback)
Burning bridges? Naw, you're being overly dramatic. It's companies like MS that have really burned their customers and developers. Apple's customers, developers, and shareholders are all generally very happy.
