They'll continue to sell it, because it's effectively free surveillance for them, but they certainly aren't focusing on the consumer market as a target demographic.
And with less and less windows-specific apps now a days, there's very little reason for the average user to buy a Windows laptop, especially over this new macbook.
That's far, far from my experience. What bugs are you talking about that make it "unusable"? I've been on Win11 for years and it's been no problem at all. No bugs that I can think of.

Linux powers the entire world. Billions if not tens of billions of devices. It doesn't "break all the time like a kit car". I switched my wife's desktop from Ubuntu to Debian about a year ago and I haven't heard a single complain. Not a single crash. She hardly reboots her computer. The thing is just rock solid and it needs to be: she works from home and she spends 8 hours+ on her (Linux) computer.
