Being exactly in GP situation, I would give a more charitable take.

We are not talking about a properly configured Windows workstation. We are talking about corporate PCs configured by an IT department that is completely oblivious to the needs of developers, most likely because developers are not their bosses. WSL is effectively an escape hatch.

Usually the stated reason is "security", and developers tend to do the greatest sin of corporate security: they run arbitrary code, and they even have the nerve to call it "their job"!

I don't work in corp IT, but I am convinced that people there are not stupid and they are fully aware of the "shadow IT" aspect of WSL, but they give it a pass because they are also aware that people have "real work" to do that would be impossible otherwise, given company policies.

I spend most of time in meetings and updating excel sheets.

Recently I needed a certain agent to help me automate some Excel stuff. Getting it to work in Windows was significantly harder if not impossible compared to WSL.
