Thanks for the hint and finding that clause in their terms of use.
I wasn't aware that they changed the license for contributions on the file 
exchange.

The terms I copied are from here:
https://de.mathworks.com/matlabcentral/fileexchange/71156-getting-started-with-matlab-video-example-files

I was (wrongfully) assuming that the license was the same for all downloads 
from there.

I am not a lawyer. But given their terms of use, I'd still recommend to not use 
any work with Octave that is based on their file exchange.
