While Satya might have made the change Microsoft <3 FOSS, the Gates/Balmer era was much better towards Windows developers.
Now we have a schizophrenia of Web and Desktop frameworks, and themselves hardly use them, what used to be a comfortable VS wizard, or plugin, now is e.g. a CLI tool that dumps an Excel file, showing that newer blood has hardly any Windows development culture, or their upper management.
As you may have guessed, this simply pushes out smaller devs. This used to NOT be like this. It should NOT be like this.
10 years ago I wanted to build a Love2D game, and release it for the three major OS's. The .love files are effectively ZIP archives, kinda like cartridges, but you need the correct Love2D version (they broke API compat every year or so). Windows and Mac used to be: "cat love.exe game.zip > game.exe".
Linux gave me the most crap, because making a portable, semi-static build was a nightmare; you couldn't rely on distros because each one shipped a different version of love.
Now Linux is actually becoming more viable, not because it's making that much progress, but because the two mainstream platforms are taking steps back.
You can use an ad-hoc signature to sign, but people who download the app will still have to jump through hoops to run it.
I started coding for J2ME on a Vodafone contest, based on Sharp GX20, which was using DOCOMO APIs in 2003.
Afterwards I joined Nokia, so I kind of had an idea how we, and our competition was doing in the market.
US was the only market that stayed PDA centric, with exception of Blackberry adoption, until the iPhone came to be.
Traditionally it was the only market where Nokia had issues.
