That's right.  There has been some confusion lately with the cygwin licensing
terms.  Apparently some companies have been using Red Hat's alternate licensing
for cygwin as a "Get out of jail free" card.  They've assumed that they can
indiscriminately distribute things like bash, awk, and sed without worrying about
the GPL.  Since those programs are *already* GPLed there is no way that Red
Hat's commercial cygwin license can affect them.

The commercial licensing terms that Red Hat supplies only affect any binaries
built by the customer.  They don't affect the cygwin package, in general (with
the exception of cygwin-specific utilities like, ps, mount, cygcheck, etc.).
