Comment (by fufufu):

 Replying to [comment:45 cypherpunks3]:
 > I believe the reason was to preserve the look and feel of the operating
 system. I think there are also technical issues that make it hard to ship
 the same fonts, including size constraints (correct me if I'm wrong). It's
 not too big of a deal though, since the font set is not recorded by the
 average access log, whereas the user agent is.

 But according to some possible font detection is the reason that we're
 supposed to consider our OSes compromised anyway. This whole issue is
 starting to seem a lot like an invented problem.

 Also it seems obvious to me that fingerprinting defenses should take
 precedence over aesthetics in any case.
