Hi Jay,

this is very rapidly slipping off-topic, but FYI:

One of the  typical reason is quite simple and (unfortunately)

If you openly document how your hardware works, then you are inviting
patent trolls and patent lawsuits.   If they can go to court and show
your own documentation as evidence, you will have a hard time arguing
that the documentation was wrong.

If the documentation is not publicly released and under NDA, than any
patent troll getting hold of it (and/or their collaborators) would have
been violating the NDA.

If there is not documentation, then the patent troll would have to
actually do silicon reverse engineering and invest money and time before
they have evidence.  And then that evidence gets questioned, and the
process how it was obtained.  Possible, but much more effort.

The point is not whether a given device infringes a patent or not.  The
point is simply that there are companies out there who simply pick the
easiest targets.  And unfortunately those that have open documentation
are easier to attack than those that don't :(
