> Wine can run apps that access hardware without issues.
Depends on the hardware. Stuff like mice, keyboards or game controllers yes, as long as they're supported by the host OS stack (don't get me started on bluez and the clusterfuck that's Linux audio in general). But anything dealing with user-mode USB drivers (looking at you Samsung ODIN or a truckload of webcams) or more exotic hardware is out of luck.
> Governments do this to themselves. The USG doesn't even have to pick Microsoft. They could potentially sign contracts with Apple for workstation hardware and services, that would encourage and feed the alternative ecosystem based around Apple, or they could fund Linux, etc. They don't though.
Apple shot themselves into their own foot here by completely discontinuing their Intel x86 lineup. You can run Windows stuff on the M series SoCs but performance is atrocious (unless it's ARM Windows, but good luck finding software compatible with that oddity, no thanks to Qualcomm here who couldn't be arsed to put out actually usable chips for years).
As for Linux, there is already a huge amount of government funding into Linux because of servers and their support contracts. That's how RH, SuSE and the other commercial Linux distributions are surviving. The problem is the desktop software stuff, here the chicken-egg problem comes into force - and made worse by the fact that unlike Microsoft who can just decree whatever they want and the rest of the world has to accept it, FOSS projects are mostly driven-by-consensus, and if you're a commercial or government entity needing a feature you have to either fork off with all the cost that entails or herding cats and playing petty politics with people from all around the world (who might just block your idea out of principle after finding out you're working on behalf of the government/Monsanto/whoever is problematic these days, on top).
