I think it's pretty clearly an anti-competitive move that could seriously harm the technology sector more than any other tech acquisition (probably).
I'm not surprised that many governments are investigating it, but I do not expect them to look capital in the eye and say "no".
What is interesting is that the UK government is investigating it on "defense" grounds. I could see a world in which they'd block the acquisition for that reason.
What do you think?
It probably using it, most mobile devices user ARM processors. It's an incredibly efficient low voltage chipset. The raspberry pi uses it too.
