I read over that statement from Unisys that someone posted. It said no 
inadvertent infringements would be pursued, and that no fees or license was
necessary for freeware using LZW. I recall that GS Shrinkit was originally
supposed to be commercial but was released as freeware due to a legal snag.
Guess we know why now.

I'll look up the Aladdin mail address. We can start an email pestering campaign
