Komodo in violation of Mozilla Public License?

[Terry Reedy]

from http://mozilla.org/editorials/mozilla-overview.html

[Occasionally the multiple roles played by a contributor cause confusion.
For example, Netscape is a major contributor to the Mozilla code. At the
same time, Netscape uses the Mozilla code as the basis of its Netscape 6
product. This has caused some people to mistakenly believe that the Mozilla
code and Netscape 6 are the same thing. This is not correct.]

 Anyone is free to use Mozilla code to create a product, and to combine
Mozilla code with other code to create that product. Netscape does this,
starting with Mozilla code, adding a set of Netscape specific items and
additional code, and creating Netscape 6. Anyone is also free to use a
subset of the Mozilla code in a product. Many companies do this, using the
Gecko layout engine, for example.
