Yes, correct i miss understood what as the bug report about.

Well i always avoid using PLF freetype and for what i have read in
ML's all the users that answered to it said that also avoid PLF
So far for hat i have seen, all users prefered like fonts were
rendered wen patents were still valid...

Well this way users cant also set to have autohint, seams theres
always some app failing.
Why not having it disabled by default? users will always be able to
set their preferences about using or not autohint, but that way
ensures that all fonts are better rended.
All this came up after patents end in wich showed users how fonts
appear poor rended, until that point i didnt saw any complains about
fonts, and this is what should be fixed.
