>This is an appeal to authority, a logical fallacy

Fallacy fallacy.

The appeal to authority fallacy would be to claim it's ok for them to do it because they're the best. The OP did not write that.

The OP wrote that on the spectrum of how to be worried, since this vendor has a track record of good behavior, and since the EULA pieces are pretty reasonable for the vendor to manage the software (which most film makers likely don't care to manage), that it's more likely that this will not be the issue that some make it out to be.

Stop making everything a (false) fallacy claim and simply address the discussion.
