I believe that's because the usual way to write a GIF file is to use LZW
compression (as presented in the GIF specification). Unfortunately, Unisys
holds the patent on the LZW algorithm and demands royalty fees for any encoder
using the algorithm. There are plenty of GIF encoders available on the web,
but, as far as I know, with the exception of ACME's, they are all part of a
commercial package and require compensation.
Unisys, however, does not require royalties from software that *decodes* GIF
files, so it's perfectly fine to write all the decoders you want (apps that
take a gif file and display it).
