Re: JFC! do they actually test anything these days
Not sure about "want". They're selecting from what's available. I want an electricity supplier that responds to customer concerns promptly without a load of runaround, with customer services that service the customer, not the organisation. But I'm not delusional! So I pick one.
MS gained ground, in part, by buying out (eliminating) competition. AFAIC, that's absolutely fine, it's a free market. It further retained that ground by creating vendor lock-in: contractually and by creating a perceived dependency on proprietary data formats. With a wee dash of sales spiel.
Until recently (say 2-5 years) application software required by SMEs, while available, weren't comprehensive on alternative platforms. The developers were raised on Windows at school (lock-in) so came out knowing that dev stack, so the majority of apps were developed on 'doze (meaning reduced training for software houses). Historically, software houses of expensive software (eg. CAD, DTP) were happy for students to use pirated software, as it ensured that when those students hit the market, they were au fait with that product: less training overhead for their new employer, stability for the software vendor and further OS lock-in. As most of the applications were on Windows, that created further dependency on that platform.
Now the up-and-comers have access to the web they can explore beyond that lock-in, so that situation's changing. Businesses are not now totally dependent on proprietary data formats, which is a good thing. But existing businesses will still stick with M$ as it's a huge professional risk for an owner/C-Suite to ditch the established and try something new. Only new organisation really have that option, which requires their education (by the IT industry) and understanding, without just following the flock.
I think what people (businesses) want are stable tools without monthly headaches and bullshit. People (home users), well, that depends on whether on not they can play their favourite games or use their desired sequencing software.
 If they could buy-out Linux, they would. But there's no one to pay off.
