Nah, they were too busy dreaming up other ways to try and discredit the news. Like the claims that it is only a mock up which was rapidly changed to claims that it is a 'ground demonstrator' that could only taxi around but cannot actually fly; when she flew, there came the claims that she is a one-off tech demonstrator and that she doesn't have weapons bays; when pictures of weapons bays emerged, it was claimed the J20 is a 23m monster that will only be able to fly fast (and not very fast because she is underpowered and DSI prevents it going faster than M2) and not be a true all round air dominance fighter like the F22; to this day, there are still people who insist that the J20 is 23m+ and is a stealth striker and doesn't have nearly enough wing to dogfight.
These claims are all made or championed by the same sort of people, and they ate wrong so often that it really isn't much of an accomplishment or surprise when their claims are proven wrong, as usual.
People like that probably have to look the word 'shame' up in dictionary.com to know what it means.
