Maybe if you are going to slag someone off you should be bothered looking for the tweet you base your slander on...
However, he's being asked by multiple people right now for the radar# and he's ignoring the questions. He just said he's known it for two weeks, which might have been too late for Apple to fix it anyway.
As an example, I have a 32GB iPod Touch that I've been using for all of the iOS5 testing for my applications and I'm only using around 600MB total. I'd never run into this issue either unless I loaded this up with tons of other apps and movies and music.
Whether he hits the limit regularly or not is another question...
