This includes terminal emulators. The last time this actually hurt me
was with some version of minicom some years ago whose idea of 'vt102'
emulation different from the idea of 'an ANSI-compatible terminal' the
then-current 'busybox master bullfrog' (Robert Landley) had. Of
course, the result of me pointing this out was not 'oh well, I might
have been a tad bit wrong about that' but a crescendo of "go away,
spammer!, you don't exist !!" shouts, as can be expected in such a
situation (the other common issues would be a 'dumb terminal' output
device, eg, a straight socket connection which ends up writing data to
a file).

If you have a just cause of grief regarding a specific problem of a
terminal control abstraction layer which enables supporting more than
'whatever happens to work on my present laptop' without changing the
software, trying to remedy that would be a good idea. Otherwise, this
should be framed as the philosopical stance it actually is: I'm
convinced that everyone who has a problem I presently don't care about
is a minion in the force of satans and ought to be burnt at the stake,
ie, drop the pseudo-rationalization of "it works for me and I damn
fucking sure don't care about you". That's at least honest.
