1. It's not "fundamentally inferior". It's just, historically, focused on a different type of user. Linux is for people who want a lot of control and power but don't mind learning how to use a command line or config file. Windows is more focused on typical users who just want things to work with GUI config tools and still be somewhat flexible. You also need to keep in mind that many new users have grown up on iOS and it doesn't even occur to them that things can be customized in more than superficial ways.

2. Linux has, historically, been fundamentally inferior for some purposes. Lots of (sometimes very expensive) equipment has proprietary drivers that only run on windows. You'll find old versions of windows running hardware in labs all over the world. This is minor though, compared to the mainstream office and home user, as well as gamers. If a typical joe uses windows and MS office at work, its only natural to do the same thing at home. Why learn a new OS for your home computer if you're only using it a few hours a week? Gamers, of course, are still locked into Windows for some titles despite Steam's best efforts. Some gaming hardware still doesn't support Linux properly (I'm looking at you, Razer). Linux is getting really close to Windows for gaming though.

3. Windows was actually a pretty nice OS for a while, until the recent slide into Microslop silliness.

"Integrating AI where it’s most meaningful, with craft and focus: You will see us be more intentional about how and where Copilot integrates across Windows, focusing on experiences that are genuinely useful and well‑crafted. As part of this, we are reducing unnecessary Copilot entry points, starting with apps like Snipping Tool, Photos, Widgets and Notepad."

While mealy-mouthed at best, I take this as indicating MS has finally started paying attention to the growing backlash and is going to back off on trying to AI ALL THE THINGS. A lot of users simply don't need or want Copilot everywhere. Many users also now have a compelling alternative in Linux. Inertia keeps them with Windows, but a significant irritant could make them switch. If MS wants to keep those users, they need to stop pushing AI so hard and focus on keeping the rest of Windows in good shape.
