Maybe you know something I don't, but I recently posted a link to an article
about the history of the LZW/GIF issue. From that article, I gathered that LZW
was used by many (like Compuserve) without permission and that Unisys was
either oblivious or didn't care about it till some time later. It doesn't sound
like it was an intentional act aimed at proliferating LZW by giving it away. I
think what's really disturbing is that in the present situation, nobody knows
if what they are doing is legal until they've had a long consultation with
Unisys and secured a license.
