Microsoft issues an update: it's supposed to update the updating system for future updates. It bricks phones.
Apple issues an update: Adds a few minor features, fixes bugs, improves web browser performance. It Just Works.
I find the trolling with "mandatory silencing of complaints" ironic since one of the features in iOS 4.3 - a user preference for the switch on the iPad to function as orientation lock or mute - is specifically in response to user feedback.
Meanwhile, Google issues an update. You can't use it until your carrier/handset manufacturer says you can (it took a month for Gingerbread to show up even on Google's own Nexus).
