I don't think there's even an argument that it can compete when it comes to integrations with mobile, other in-home devices, and other peoples data/devices. Yeah it's an issue that there are basically two walled gardens people get into, but Linux isn't even in the neighborhood. It can certainly compete on "a web browser exists and works" but my point is people actually do want more than that.
And it does break. I mean even if the drivers and necessary software is all great, at some point something weird happens and doesn't unhappen. My Fedora install has software I downloaded in the software GUI that won't update. It sends me (garbage) messages about SELinux constantly. The toast doesn't autohide and toast pops up for too many things. It's still usable, nothing is "broken", but it's death by a thousand cuts. No one wants all this confusing crap that isn't "just working". I don't get that feeling in macOS or Windows 10.
