I think "We bring tech jobs and tax revenue, which we will take elsewhere if you're not more compliant" is hard to label as anything other than a threat - particularly in the context of trying to play off the UK against the EU. UK politicians have made hay off the idea that being free of EU bureaucracy would make the UK a more appealing environment for companies; that was always bullshit anyway, but here Microsoft are trying to use it as leverage in the court of public opinion.
