Microsoft sent a patent demand letter to B&N. B&N went public as part of its defense. Microsoft countered with two separate deals:
1) Settled the patent issue privately for a revenue-sharing deal and cash payment.
2) Microsoft committed to invest in the Nook business (called New Corp by B&N) which eventually led to Microsoft purchasing Nook for a premium.
So, while the immediate settlement was probably measured in hundreds of millions, the total outlay from Microsoft shareholders to B&N shareholders was close to 1 billion even though it was spread over multiple and disparate deals.
Prior to the patent letter neither company had a significant relationship.
All the big companies take part in this little dance.
What Microsoft does is very different to that and very arguably close to the definition of extortion.
It's just that some companies don't like to pay what's due, which is fine... It's their right and they can settle it in negotiations or in court. The problem is, due to the current media atmosphere that is conducive to inflammatory rhetoric because it garners rageviews, these companies now also like to complain loudly using words like "extortion", which the tech media eagerly parrot. And then others who don't like the licensor (or patents in general) pick up that rhetoric and run with it.
MS has hundreds, probably thousands of patents in their portfolio. A single patent makes negligible difference to the portfolio.
In addition, MS has prevailed in court with several other patents in many other jurisdictions, so clearly they have enforceable patents in their portfolio. That is why they can rightfully continue asking for licenses.
This is one of the "practical" problems of licensing large portfolios that I alluded to. The quality or fate of a single patent does not reflect on the entire portfolio. Conversely, invalidating each patent or valuing each patent is also incredibly complex.
There is an entire field of specialization for valuing portfolios. Calling it extortion is mostly the efforts of one side of the table to exert indirect pressure on the other

In any case, they settled for a negative value a lawsuit alleging B&N violated Microsoft patents. If that doesn't send a message about what those patents are, I can't imagine what would.
