I know that a few years back before WSL was even a thing someone at Microsoft "leaked" that some departments were using macOS almost exclusively. I would be surprised if the decision makers who force all that crap into Edge actually dogfood the product. WSL, Azure and Windows Terminal are a different story though, which might explain why they hold up and aren't overloaded with bullshit.
