Did anyone *force* Nokia to bring in Elop?
Then Nokia's woes are entirely their own damned fault.
They had Symbian... and let it wither and die through under-investment.
Their in-house System 40 OS has seen precious little love over the years too.
They mucked-about with various Linux derivatives and... f*cked those up too.
By the time Android had reached the point where it could no longer be accused of being a flagrant iOS rip-off, it was too late for Nokia.
The writing was on the wall when Apple launched their first iPhone and subsequently proceeded to eat Nokia's high-end lunch. Nokia *should* have seen multi-touch devices coming. They didn't. Neither did most of the other incumbents of the day: Whither Sony-Ericsson? Where is LG? Even Motorola is now just a department of Google, Inc. Nokia's management became complacent and, ultimately, incompetent. Today, all they have left is their mobile networks business; their mobile arm was effectively junk long before Elop knocked on their door, so offloading it now is more a case of "What the hell took you so long?" than "Ooh! Elop was a Microsoft mole!"
This is what competition *means* in a (mostly) Capitalist society: Company A seizes the castle and gets to play king for a while, making it the target for all its rivals. Unlike those rivals, Company A only has to make one serious blunder and one of those rivals will come along, spank their corporate arses, and take over that castle. It then becomes that new company's turn to rule for a bit.
Rinse and repeat. This corporate success / failure churn is cyclic and fairly predictable.
It's also why the most successful CEOs don't tend to be nice, friendly little doormats. You don't get to demand such telephone-number deals and salaries unless you have a ruthless streak wider than an airport runway.
