The Ubuntu font and a fresh look at open font licensing

DejaVu doesn't extend Liberation, it extends Bitstream Vera.

This line is inaccurate and mixes up various parties:

"Crossland believes that this spectrum would best be served by a clear
set of license choices, along the lines provided by Creative Commons
for artistic works. The Open Font Library's goal of creating strong
copyleft fonts, for example, might best be supported by the GPL with
Font Exception. SIL's interest in attracting professional type
designers to work on modifiable, redistributable fonts is best
supported by the OFL."

With my time machine I would rewrite that as:

"Some have suggested that this spectrum would best be served by a
clear set of license choices, along the lines provided by Creative
Commons for artistic works. The Open Font Library's goal of creating
an easy way for hobbyist type designers to contribute fonts to the
commons, for example, might best be supported by the OFL. Dave
Crossland's interest in attracting professional type designers to work
on modifiable, redistributable fonts is best supported by the GPL or
another source providing licence."

The OFLB totally isn't about stong copyleft fonts, and saying that gives the wrong impression about my influence over the site; which is considerable since I've tried to get the site's codebase improved substantially over the last few years, but I do make efforts to involve the views of other - especially Nicolas Spalinger (yosch). I believe that for the OFLB's goal - simple contribution for casual designers - the OFL is the best choice. For professionals, source provision is key to libre business, and being professionals, they can easily shoulder the responsibilities, and really reap many benefits from sources.

Finally, "the free software movement has never been held back by supporting multiple license options" isn't true, the free software movement is otften held back by incompatible licences since that prohibits mixing 2 programs under eg Apache 2 and GPL 2. It has succeeded despite this though, which I guess is your point.
