Can somebody summarize the issue? I was thinking that wayland and Xorg are different projects? So what is the incentive that people stop using X11? It is also not like Python2 where any effort to support it further would retract ressources from Python developers developing Python3. (And compare that to Perl6 developers renaming it "Raku" and continuing to support Perl 5, or SBCL developers just quietly adding support for Unicode -Python3's most consequential change - without breaking existing stuff?)
And one thing more, we saw companies taking influence in Web standards like HTTP 2.0. Yes, it is still open standard and supported by FLOSS software - but one cannot deny that many development in the modern web like advertising, tracking, data collection, and centralization are not in the interest of users, and this us why the interests behind specific standards matter. Technology is not free of interests and technological change is not automatically in the interests of users.
