<p>I think a few of the statements are incorrect or not clear. My
comments strictly address those items that discuss
Khronos-developed material. <br>

<p>There has been no change to the Khronos IP policy. The full first
paragraph of statement in the draft specification is:</p>
<blockquote>
<p>This specification is protected by copyright laws and contains
material proprietary
to Khronos. Except as described by these terms, it or any
components
may not be reproduced, republished, distributed, transmitted,
displayed, broadcast,
or otherwise exploited in any manner without the express prior
written permission
of Khronos.</p>
</blockquote>
<p>Note the important clause at the beginning of the second
sentence: "Except as described by these terms". The subsequent
paragraphs provide the terms, specifically:</p>
<p><br>
</p>
<blockquote>
<p>Khronos grants a conditional
copyright license to use and reproduce the unmodified
specification for any purpose,
without fee or royalty, EXCEPT no licenses to any patent,
trademark or other
intellectual property rights are granted under these terms.
Parties desiring to
implement the specification <b>and </b>make use of Khronos
trademarks in relation to that
implementation, <b>and </b>receive reciprocal patent license
protection under the Khronos
IP Policy must become Adopters... [bolding is mine - ld]<br>
</p>
</blockquote>
<p>If you have no interest in using Khronos trademarks or receiving
reciprocal patent licenses, then you do not need to become an
"Adopter".</p>

</p>
<p>There is no programming required for the Interactivity extension.
glTF viewers that correctly implement the specification handle the
data that is stored in the glTF file structure and act according
to that data. The data is not code (JavaScript or anything else).
Also not that "animate" means any kind of change to the model or
environment.<br>
