I'd also argue that (a) the differences between the Linuxes aren't as
big some people would make it out to be --- especially compared to the
differences between AIX and Solaris and HPUX, and (b) *BSD and macOS
has their ports and homebrew systems which also ease any pai that
isn't handled by autoconf and friends.

In addition to that, a lot of user-desired functionality is made
available via dynamic web "appliances" (e.g., GMail, Concur for those
people who need to submit travel reports) as opposed to compiled
binaries.  I'm talking about pure web applications, of course, not
Java web apps.

My horror store from when I was working at IBM was that their expense
reporting tool was written in Java, but it only worked with the Sun
JRE.  But if you needed to use to configure an IBM Bladeserver, that
only worked with the IBM JRE.  So if I needed to submit an expense
report, I had to kill the browser, set the environment variables to
point at the Sun JRE, and then restart the browser and do the travel
report.  And then when I needed to go back to messing with a Blade
Server chasis, I had to kill the browser, and reset the environment
variables, and then restart the browser.

Ah, Java.... write once, debug everywhere.  :-)
