I think of Micro$oft as being a massive, conning money grabbing, monopolistic/partly-cheating company.
sadly its all True. the irony is it all started with a backlash against money grabbing, monopolistic BIG BLUE IBM !
maybe its time for the next OS backlash or IT disruptor.
I'm impressed that you noticed and knew about the IBM situation and connection.
Fortunately, I think we may be heading towards a solution.
If other OS's, such as Linux, become more popular and windows less popular. Linux (or at least a non-windows OS) may get to the point of
CRITICAL-MASS. I.e. So many users, use it that someone creating a game or piece of software, will then need to write it for Linux as well as Windows.
The increasing likelihood of cheap, Arm based desktop (and other types), may mean that it becomes popular for them to have Linux on, as it won't have the horrible Micro$oft tax on it then.
Much like Mobile Phones and low end tablets, which tend to be Arm and Not-windows, e.g. Android, IOS, Chrome etc.
But I agree some of them are Intel cpu based as well, especially Chrome books.
I think companies such as Google or Apple. Were best placed to challenge Micro$oft. But sadly for various reasons, that has not happened.
E.g. If Apple would sell the MAC OS, for ALL PC's.
Or if Google could have produced a better desktop OS, also for PC's.
But sadly Apple seem to want to sell (arguably) overpriced Apple Macs, and Google prefer to be "internet/cloud" based, e.g. Chrome book.
Anyway, I hope this situation gets fixed, sooner or later.
tl;dr
You can probably tell that I would be crying for weeks on end, if Micro$oft was to be sorted out (e.g. legislation), taken over and FIXED or go bankrupt. Or if a decent OS, at a reasonable price was to appear as competition.
