That is kind of offensive. I would never do something like that. I have never
intentionally violated a license. I always give credit when credit is due.
You're misunderstanding me, I’m describing the conditions under which we can
change the headers to ALv2. In some cases you have taken a 3rd party file,
modified it and you added your BSD header on them, that fine, but depending on
the extent of the changes we would either replace your header with an ASF one
or remove your header and leave the original 3rd party header. This is not that
you’ve done something incorrectly or haven’t given credit, just that ASF policy
differs to how you’ve been working in the past.
Yes I did misunderstand you. It implied to me that you though I was
just removing third party copyrights and licenses and replacing them
with my own. That does not happen.
In December I did count this (see also attached):
nuttx/ apps/ TOTAL
Total Number of (regular) files: 13792 2961 16753
Total Number of files with Copyrights: 10918 1931 12849
Total Number of Copyrights: 12107 2234 14341
So you are really only concerned about those file that have multiple
copyrights. For the files that have my Copyright I can think of three
reasons why you might see "Copyright" more than once in the file:
* Yes, when I leverage third party code (usually into apps/), I add my
information to the file but retain the original third party license.
* There a several cases where people modified files that I wrote and
decided that they need to add their own copyright.
* And there is the case where I developed an original file, but used
information from other sources to design the code. The typical
situation here is the use of sample code provided by a silicon
vendor as a technical reference. In that case, none of the vendor
code is in the file, but for some trickier register operations such
as configuring timers, the logic sequence (only) comes from vendor
sample. In these cases, I give credit to the source of information
along with versioning, date, and/or Copyright information
But I have doing this for a long time and for many files. I was pretty
ignorant about licensing a dozen years or so ago, so there could be most
any error in older code, particularly.

Here is better, more complete data about the Copyrights in NuttX. The apps/
directory does contain a considerable amount of ported 3rd party code which
which throws thing off a bit. The core OS is exceptionally clean with mostly
original code; the applications are a hodge-podge of original and ported code.
Identification of Copyright notices was accomplished using 'grep'. It is prone
to some errors in that it does not understand the context of the Copyright.
Some of these may not be Copyrights on the file itself be some reference to
other Copyrighted material. 'grep' isn't smart enough to know the difference.:
This should be a complete accounting of all Copyrights other than any possible
(probable) human errors. The executive summary is that I hold 88% of
copyrights. 171 other people/organizations hold also have Copyrights.
