I know this might be a controversial take but nevertheless I will state my opinion: I do not think "the year of the Linux desktop" is the good idea that most people seem to think. Everything that gets the eye of Sauron on it proceeds to become a complete mess.
Resources always win. All that is needed to ruin an open project is dump money into heavy development up to the point where it becomes impossible to do without it. Plenty such cases already.
This also ruins the development of the project akin to feeding wild life, you get them dependent on you, and if you stop feeding them they lose the ability to feed themselves in the wild. Such is the Linux ecosystem, based on a type of work that so far made a great project for people who have a bit of technical skills. Making it more accessible to the masses only brings that kind of bullshit into it. Inevitably. There is no way something of such importance, to the masses, won't get corrupted in one way or another. That never happens, if there is too much interest there will be funds dumped into corrupting it, one way or another.
The best path forward for Linux was as before, to fly just under the radar, to bee a bit too complicated for most people. This is what protects it. Most, if anyone, don't seem to understand this very simple fact. No older Linux user gets anything worthwhile out of this deal, nothing relevant, just inevitable enshitification of it. Historically proven over and over again. I find "the year of the Linux desktop" to be a childish take in a world that functions on completely different principles.
edit: To add a bit more context, Windows is not the mess that it is today because of evil Microsoft, it is a reflection of its user-base. Same with Linux. They did that to Windows, with their behavior, with accepting all that nonsense.
You want to bring the very same type of people, with that kind of attitude, in Linux, what exactly do you thing is going to happen? They will adapt to Linux mentality or they'll proceed to ruin Linux with their behavior? I can take a good guess on what will happen. People will people, and corpos will corpo to milk them.
Linux is already integral to the tech and enterprise worlds, which have a lot more money to throw around the consumer desktop space. I'm having trouble seeing how Linux becoming a more popular consumer OS would lead to the types of problems you're talking about, if being a leader in the server space hasn't already led to them.
Also, Linux has a built-in mechanism against enshittification, which is its open source and multiple flavors. Ubuntu becomes enshittified? Move to Fedora. You can have a dumbed down consumer-friendly distro without affecting Arch.
