The theory of Elop destroying Nokia (consumer) makes sense, because he was at Microsoft, went to Nokia sold it to Microsoft at diminished value and stayed there for a good amount of time. But who would pay Musk for this? And how will he be compensated? Afaik, he's lighting a bunch of his own money on fire. Although, there has been a lot less news from him on Tesla and SpaceX, so maybe it was all a plan to keep him out of those spaces.
