Sure they would like to screw MNTA if they could, but not at the cost of their own credibility.
FWIW I think it is indisputable that TEVA blusters in their statements. I will put together a list - but example numero uno would be the claim they made after Momenta approval "Hey, our approval is coming in n months because we submitted our immunogenicity data n months after Momenta". That is completely bizzarre logic - and they would have to be either idiots (which I think highly unlikely) or blusterers to make such a statement. And if they are blusterers I think it is completely expected they would tone it down when threatened with a lawsuit.
Also note that they made explicit reference to their lawyer being on one of the telecon's immediately after the lawsuit was enjoined. Again speaking to a filter for legal reasons.
But, as I said, I think there are plenty of other examples and it might be interesting to compile the list.
