That said, the "Who is happy about this?" question smacks as slightly unfair given Gruber's unabashed approval of Apple's decision to not support Flash (albeit, I too support this decision as a web developer).
Addendum: whereby I mean to say that there are undoubtedly numerous users who have been "harmed" (whether they know it or not) by the lack of Flash on iOS devices (e.g., because they could not view a given website on their device), even if the removal of Flash will be good for the web in the long term.
