Alternative explanation: people complain when something they know
changes. Nobody could stand to use Macs if bitmap fonts were the
pinnacle of on-screen legibility.

Yep :)

True if you use bytecode hinting. Now use hintslight/the autohinter for
everything. Suddenly everything harmonizes much better because the same
hinting strategy is applied consistently to everything. This is the
reason I pushed for hintslight as the default in GNOME and FontConfig 
after Ubuntu used it for years.

You can't fix fonts having different hinting strategies, unless you
rewrite the hinting.

Find out in FontForge, or if you have fonttools installed, look for
"CFF" in `ttx -l font.otf`.

Lemme reword that: users of apps whose developers switched font engines.

Maybe you find that you prefer what you're used to :)
