Seriously, how on earth are you coming up with this? Time and again they debunk those silly claims but people just keep bringing this up on and on. Is it some sort of conspiracy theory?
I don't think there’s any serious evidence of it being true though. All we can see right now is that there are a surprising number of MIT-licensed packages replacing GPL-licensed packages. It could be a coincidence.
We sigh in relief every time we see a software that we rely upon changes/adds non-viral license such as MIT, Apache, MPL, BSD, and so on.
