That opinion is flat out ridiculous. Or maybe it makes sense if you
think consumer desktops are the be-all and end-all; but they are not.
(If you do think that Apple's decisions are an important factor here,
why are you so much not on board with pushing ARM? Apple's certainly
doing their darndest to make ARM a mainstream arch.)

And that opinion is simply wrong. You have provided no justification
for allowing Fedora to get boxed in on a single architecture, which is
the inevitable end result of the thinking you espouse. Pointing at
individual deficiencies of individual arches is not a justification;
especially not in view of all the problems x86 itself has got. The
Linux community has slowly worked around x86's limitations, the same
could happen for any other arch. The only reason this doesn't happen is
people trying to justify not putting in the work by rationalizing that
"that architecture is obsolete" or "Intel is the top of the heap today,
so I don't need to bother thinking about anything else". Or in other
words: you sir are not part of the solution, you are part of the
I'm not saying that I think ARM is the ideal other primary arch, but
it seems to have more momentum than most of the other choices. We
should be looking for ways to make it a PA, or make something else
a PA. We should not be looking for excuses for monoculturalism.
If we settle for that, we'll have only ourselves to blame when we
become irrelevant, not too many years down the road.
