> Take most popular Linux distribution — X.Org is not there.
Android became popular because it had just one competitor among high-end devices and no competitors among low-end devices. (And because Google have done good job advertising it)
X.Org have nothing to do with android popularity. Android was initially developed for small screens, single full-screen window, no multiple monitors, it used a simplified graphical system (and now it's not that good on large screens because of that).
> Take most popular linux laptop on Amazon — X.Org is there but it's not accessible and there are plans to rip it out altogether.
The cheapest laptop should be the most popular, isn't it? ;) Or do you think its low price could be caused by X.Org absence?
> X.Org is "pearl of dying Linux world".
Linux is not the most popular desktop OS, that's right. Why? Because it was not among the first! Android came to a semi-empty market and filled it. But desktop Linux came to a market, filled by Apple (a little) and Microsoft. It had to fight for its future, and one of its advantages was X11: desktop workspaces, many DE/WMs to match everybody's taste, multi-monitor support, multi-seat and X-terminals with the network transparency that people like to talk about so much — its features and design were so good that now we have at least basic X11 support everywhere, on Linux, Windows, MacOS...
In those early times when X11 was like modern Wayland, there were about 3 Linux distributions and nobody have even heard about Linux. What do we have now? Most people know about Linux and many of them tried it.
Without X11 there could be no desktop Linux world at all.
