Of course he's going to say positive things. If you're in a position where you've just recently left your job, you're not going to bad-mouth your previous employers, simply becasuse it'll come back and bite you in a lot of job interviews, e.g. "John we checked with your previous employers and they said while you're a talented developer, you have a bad attitude, argue with superiors a lot, and publicly disclose confidential company data. What skills do you think you have that will compensate for these big and obvious defects?" and he's going "Oh stercus, he's going on about the big F-U I gave 2K games on twitter and other media within a week of leaving them. What do I say?" This applies whether he left the job of his own volition, was told to jump or be pushed, was pushed with the semblance of jumping or straight out fired (although there is some chance of the F-U in that case as you don't depend on a job you're fired from for references).
Read my previous comment. There was no need for him to say anything. I didn't say he would bad mouth them, but he also didn't need to say anything. He doesn't tweet much at all.
