Yep!  The thing we need to bear in mind is that Welch, etal, were
pretty well compensated by the customers to which they had licensed
the LZW algorithms.  The "free" users were paying nothing to LZW,
and were causing LZW's licensed customers to wonder why they were
paying big bucks for algorithms that were being universally used
for free.

So, even though GIF (which had nothing to do with LZW, other than
infringing the patent) lost its great market share, that happening
had no apparent effect on LZW's bottom line.

A different company (Microsoft), when faced with a very similar
situation (MSBasic on CPM systems), leveraged the publicity and
good will provided by the free users, into the leviathan company
that is Microsoft today.

LZW took the straight hard line and eschewed the fame and glory
that came with being the heart of the GIF adhoc standard, and where
are they today?

Business is a tricky business.
