That's a whole other can of worms, too. How about reproducibility and transparency? How do I know the math is correct when I don't know what MATLAB/whatever is actually doing under the hood?
But, moreover: how can my research be reproducible if someone else can't afford to buy that specific software? Or if the software's version I used is outdated and the updated one does not read the old one's files?
