I find Windows to be a hindrance (I've used it from v3.1 to 7, so it's nothing to do with unfamiliarity).
Microsoft may be trying to become developer friendly - but their OS certainly is not, and increasingly so.
Windows isn't the only OS that has a graphical IDE - likewise Bash is available on Windows.
(all of my tools are available on both systems)
Sure it has, because it springs from the developer culture on each OS, and the main reason why good UI/UX research is so hard on GNU/Linux systems.
It is always an uphill battle, as GNOME and KDE devs know about.
Also note that I pair macOS with Windows on my list.
Windows 10 has gone for the hybrid UI; both "modern" and traditional. At the same time.
I'm not sure why you say it's hard for UI/UX research on Linux, when there are so many different desktop environments and toolkits - all(?) of which are theme-able. On Windows, you're stuck with one. Well, both.
Hence ChromeOS and Android in what concerns consumer devices, where Linux just happens to be the chosen kernel but nothing prevents Google changing it for something else.
Many devs using Linux do too. Every single one out of many many dozens of Desktop Environment and/or Window Manager combinations let you enjoy all these. Just a matter of familiarity. VS is certainly a neat IDE and always was since I first played with it ~17-18 years ago, but hasn't been the only player in a long time now. Unless you need to use every single feature and tool from its up-to-120GB of installation size (with everything selected) --- never met anyone who does..
There is this culture of tiling window managers, vim, Emacs, everything done via CLI and UI/UX is a subject of interest only for dumb users.
Which surfaces as the biggest one among its users.
So anyone that cares about programming pleasant UI/UX workflows, hang with developers that share the same love for it, only has macOS and Windows dev cultures as harbor.
The sheer amount, variety and quality of themes available for a typical Linux distro puts your point to rest.
Until there're Adobe Photoshop & Illustrator for Linux, no professional UI development is possible on that OS.

There are plenty of great tools that really doesn't require these overly priced tools.
I’ve been developing software for 17 years, and this always was the case, regardless on the industry (desktop software, embedded, videogames), regardless on target platform (PC, mobile, embedded win or linux, game consoles).
I know there’re other good tools, but I’m not in the position to force everyone else to stop using Adobe.
To export just use a cli program and batch that process.
Imagemagick to convert psd to png `convert file.psd[0] file.png`
Imagemagick to convert ai to png `convert test.ai -channel rgba -alpha on test.png`
I don't use anything Adobe, yet I don't remember having a problem opening such files (regardless of OS).
If so, I'm not afraid to respond with "Hey, can you export/save as in <some other format>?". It's not like I, a developer, am going to be making changes to the file and send it back - let alone pay for a product with which to open it.
I wouldn't give them a .c file.
Personally I just make scripts and view the output file to check for quality. I use ImageMagick mostly but Gimp and Inkscape also have command line interface.
In your opinion.
I'm a professional. My skills relate to the domain/subject, not a specific software package/language/library. I'm able to transfer my skills and learn+use alternatives - and co-operate with those who aren't.
YMMV.
