Hey, you already asked this in another thread.
None of us here work for Avid. They are the ONLY folks you should contact if you are having questions about their eula.
Most people here just use DNxHD as an intermediate. If you don't use it to deliver commercially, I don't see that there would be a problem, but I am not a lawyer.
Although not like-worded, the Sony EULA on this site says essentially the same thing. So does Google, Dropbox,
Facebook, and Youtube, to name a few. They own you.
