People always talk about “the year of the Linux desktop” (and not always ironically!) but honestly, whether a random person can play 4k Netflix on their Linux laptop is like 0.1% of why Linux matters in the world.
You're being disingenuous. Linux users are users of Linux and software that runs on Linux.
In the context of service deployment, this clearly refers to users who need to deploy Linux VMs to run software that runs on Linux.
The kernel is irrelevant. This use case clearly refers to Linux distributions, which nowadays probably means Debian or a Debian-based distro. So obviously in this context a Linux users means someone who needs to deploy a Debian-based distro on VMs to deploy and run software on it. In fact, more often than not when people refer to running Linux they are actually implying that they need to deploy and run software on a specific ecosystem, such as a combination of a package manager, package repository, service manager, and even f Directory tree layout.
This is not a way of life or a cult. It's a technical requirement that must be met for people to do their job.
That's exactly the point I was making. People who run Debian-based desktops are a tiny subset of that group. Hell, I have a Linux desktop and not even I run Debian.
Microsoft may or may not “love” the tiny subset of users who run Linux-based desktops and are unwilling to use web applications. But that doesn’t mean they don’t “love” Linux as a foundational technology of modern computing.
