A stupid amount of non tech users manage to use it

Meanwhile, most of those users are running systems that are so deteriorated that it takes them a minute+ to open a browser.

On a machine that they only use to browse internet.

Not without stuff breaking constantly

My parents can't use windows but they can use Linux - their windows was covered in "you need to update" and OEM thingies asking them to consider the premium package and shutting down against the user's will and adverts for onedrive and that ridiculous universal search feature that can find things on Bing but not your My Documents folder and the antivirus showing distressing messages about how your PC is dangerous unless you pay for the deluxe service. Not all of that is "Windows" it's true but it's partially Windows fault that uninstalling things is so difficult - some things are on the "add and remove software", some aren't. All of that is standard part of the Windows experience on the Windows ecosystem, even if it's not all intrinsically Windows. So I put Linux on their laptop and GNOME just lets them easily use their browser, email and files without needing to dig through settings to disable tracking, without shutting down against your will, without saying you have to buy new hardware to update versions.

So there are points on both sides but don't say that Windows is unarguably easier.

Edit: not to mention that using a package manger's GUI is clearly easier - and easier to do safely - than getting software by surfing the internet for MSIs and EXEs.
