Everyone in the software sector I know has moved or is moving to macOS X or Linux.
Gosh, that would suggest that pretty soon there will be no more software for Windows -- I'm scared!! Or wait, maybe it suggests that you only know people in a certain, narrowly defined slice of "the software sector"?
I can't give you actual details, I can only tell you what I know to be public knowledge, but I work as an external developer with/close to or in advisory to a LOT of Microsoft beta and testing teams (I'm currently working along side the .NET core 3 and Blazor folks) - however... this does put me in a position that I do often find out "stuff", which for obvious reasons I'm not allowed to repeat.
Public knowledge (No matter how thinly spread it is) is allowed...
Right now, if you are a business with less than 1000 employees, AND you have an enterprise site license, AND your moving to windows 10, you can NO LONGER get physical media to install Windows 10.
Instead, you get a log in to the Microsoft network, which allows your I.T folks to create a bootloader on a USB key, this bootloader is then booted on the PC to be installed, that PC then installs a secure UEFI bootloader on the device (Read secure as in, once it's installed it's locked down and cannot be removed [or changed/edited] - bye bye multi booting OS's) .
The entire device then boots directly from Microsofts Azure Cloud systems. From that point on, that device can no longer have any other OS installed on it, and it can ONLY boot over the network to load W10 and/or Office 365.
MS are not making any qualms about this, and have openly admitted that they are moving towards a future where windows will be a service.
If you have over 1000 employees, or are a large corp, you can get some physical install media, but in most cases, the baseband OS that is installed is still a cloud booted version. MS WILL supply a version to be installed directly on a hard drive, but you need to go through special channels, and prove why you need an offline version, which if MS decide to refuse, you won't be allowed to use "Windows as a service".
Also, if you have over 1000 employees and/or deployed OS's, you must sign up for "Windows servicing as a service", and yes that's exactly what it sounds like. ALL of your I.T. upgrade, management, servicing, patching, installing of apps... basically everything your internal I.T folks would normally do, WILL BE delegated to MS technical staff (For a monthly fee of course) this is a requirement to getting an enterprise license, and businesses using W10 in any shape or form (Unless your a little 1 or 2 man band) will NOT be allowed to license anything other than an Enterprise version.
MS Office, the current "Office 2019" version will be the LAST ever version of MS office that will ship as an install-able product.
There's still a good few years to go yet, but they will eventually roll these things out to the consumer versions too. The reason they are trying so hard to eradicate all copies of "Installable Windows" is because they want everyone eventually on "Windows as a service". For those who write software, right now is a golden time, with them giving away free copies of visual studio left and center, but it's all a ploy to get you hooked, they are slowly moving visual studio to the cloud.
And .NET core is not all nice and cross platform for the hell of it, it's heading that way, so it'll run in whatever you throw it at, when your forced to move all your software development activities to Azure too.
We'll leave it there for now......
Suffice to say, it's gonna be a fairly lengthy time before we get there, but that's the direction MS are heading, and there not making it a secret...
