Not really. It has to do a lot of font-related work to implement the web
standards but they're using freetype2/harfbuzz like everyone else.

You're getting confused by the fact that it didn't use DirectWrite on
Windows for quite some time. It *certainly* had subpixel rendering there
and on the other supported platforms.

Windows has both a legacy font rendering stack and a modern one with a
different appearance and better performance. Many applications use the
old stack but people spend a lot of time in browsers so it got noticed.

I doubt you're able to notice color fringes with black-on-white or
white-on-black with the lcdfilter set to lcdlight. You probably just
didn't have it configured correctly (i.e. no lcdfilter).
