HVD Comic Serif Pro: licensing confusion

I found HVD Comic Serif Pro on the wish list of fonts to be reviewed and packaged for inclusion into Fedora GNU/Linux. https://fedoraproject.org/wiki/HVD_Comic_Serif_fonts I downloaded a copy of the font archive file -- http://hvdfonts.com/assets/Document/15/HVD_Comic_Serif_Pro.zip -- and I read the Readme.txt file therein. That Readme.txt file includes terms which conflict with the license: and conflict with portions of the license (for the font, I can only guess) which is listed as: The top two passages I quoted above seem to me to be licensing terms. And these terms conflict with CC BY 3.0 unported: - there is no requirement in this CC license which requires a licensor to include "an unmodified copy of this text file" - there are no restrictions in this CC license against distributing copies of this font alone for a fee - attribution in accordance with this CC license can be achieved without including this Readme.txt file (one could, for example, include no such file and list changes elsewhere, or include a different readme.txt file which gives Hannes von Döhren credit and list changes in that different file) - this CC license says it is the only set of terms for licensing this work under this CC license (sections 4a and 8e). My reading of these sections say that any other terms (such as those listed in the Readme.txt file) do not have to be followed. Looking at https://fedoraproject.org/wiki/HVD_Comic_Serif_fonts it seems that Fedora considers CC BY 3.0 unported to be the only operative license on this font. But how has Fedora determined that this Readme.txt file can be ignored? I looked through the mailing list archives for this list and found no discussion referring to this font. Has anyone contacted Hannes von Döhren about this? Thanks.
