Many companies and organisations target Linux;
We have checked out BricsCAD and a collogue used VariCAD.
Currently using FreeCAD for 3D modeling.
There are CAM software, parametric modelers...
We have used Eagle CAD to produce circuit boards many years. (We plan to switch to KiCAD.)
We switched to Linux thirteen years ago, there was no reason not to.
Most importantly we do not need to learn different OS for our server, desktop, laptop, product. Linux. And there are plenty of programs and great support.
Autodesk today *do provide Linux versions* of Eagle. https://www.autodesk.com/products/eagle/blog/how-to-install-autodesk-eagle-on-windows-mac-and-linux/
Citing that page "The EAGLE that you know and love continues to work on your platform of choice, whether that’s Windows, Mac, or Linux. This is what continues to make EAGLE so popular"
So yes we do wonder when Fusion will follow in that spirit of Autodesk.
Linux and cousins runs most smartphones, servers and all top 500 supercomputers, desktops, laptops, lot of smal and big IT infrastructure, many industrial controllers etc, etc...
Dont forget iOS and macOS too are cousins to Linux. (Both are modern implementations of Unix.) Android is closer to plain Linux.
Even Microsoft nowadays have jumped on the *nix move and ships a Linux variant (WSL2) with the only Windows version left they support.
(Because many tools and server software etc are not available for MSWindows, like OwnCloud server dropped support for MSWindows due too to many system bugs)
It is probably much easier to support macOS+Linux (both are *nix) than MSWindows+macos which are much more different.
Maybe it is then not hard to kind of add support for that most different OS - as its developer already started to support programs needing Linux? (I understand graphics may be a beast)
Or, MSWindows users can install virtualisation software, install a Linux of choice to run Linux programs in. Like we Linux users do for MSWindows programs... Difference is, that currently we Linux users have to pay licens to Microsoft if we would like to use other developers MSWindows programs, which is a bit stupid.
It make sense not to support *MSWindows*, as that traditionally have been a very expensive source of problems with malware, integration problems (standards breach) etc.
Some companies make compatibility improvements so their programs can run on i.e wine, but Autodesk dont help even a small bit though potential users who could pay them money struggles... Are they paid by one of the two big OS manufacturers to not sell to the so far third biggest OS?

Addendum: Decided to try to download Fusion 360 to try either with wine or my old windows 7 in emulator that i should not allow to connect to internet, but I get: "Your operating system is not supported. Fusion 360 is supported on 64-bit Windows 7 or newer and 64-bit Mac OS X 10.12 or newer. " Autodesk really do not want our money.
