This is one of the biggest UI issues I have with Fedora post-install, the fonts are very jarring versus the whole Ubuntu/Mac/Windows experience. It's a non-ideal way to present Workstation to new users. I've actually filed a bug about this:
What I don't understand is why Ubuntu has great fonts hinting by default despite these patents being out there. Do they use a different package or configuration of the existing patent-free Freetype?

Subpixel rendering is still disabled in the Fedora freetype package,
due to patents that have not expired:
https://en.wikipedia.org/wiki/Subpixel_rendering#Patents
I think we just need to accept that we can't have good font rendering
until they expire.

Fedora supports autohinting without installing anything extra, just
change hint type to Light (codeword for "autohint") in Tweak Tool.
Autohinting does not usually work as well as normal hinting, so it's
good that it's not used by default.

The best description of Infinality I've found is
http://www.infinality.net/forum/viewtopic.php?f=2&t=18
Highlight: "These modifications essentially cause the Truetype
interpreter in Freetype to ignore hinting in the X direction, giving a
Cleartype-like result (unlike many pre-existing so-called "cleartype" packages for various distros). The default Truetype interpreter in
Freetype renders fonts "correctly", in that it follows the instructions
given to it by the font. For legacy fonts (Arial, Verdana, Times, etc.)
these instructions were created with the idea that the end
rasterization of the font would be monochrome, i.e. Black and White
pixels only."
