That's the sad real true and nobody see, nobody care.
Every company is competing with an objective: gain user preference with the best balance among selling price vs quality. No one can sell for less than total cost plus a profit margin.
When an exogenous factor is added to cost, like the M$ tax, legal expenses, lobbying expenses and the like, the compensations are: less quality (cost reduction), less profit, higher selling prices. These measures damage the technological development because funds available and motivation for R&D will be less (why shall I make an effort to invent if I know that my invention will be stolen by a shark?)
Those who collect the proceeds from royalties will not do R%D because is useless. The monopoly position allow to simply don't care. That is the reason why Windows XP had the ridicule life time of around 10 years, was replaced by a worst and mediocre OS (Vista) and at the end Windows 7 was an improvement only because someone felt some fear when both Apple and Linux showed capable of advancing in that core market.
Android / Chrome / linux / open source, have a huge potential to threaten the Microsoft's core and peripheral business. They don't need to compete doing better. Its more cost effective for them to spread FUD by litigating. Money is an asset and they have lots of it. The competitors do not. Then they use it to compete.
The consumers will pay again. More for worst, at each gadget purchase.
