It's not just foreign nationals that would be barred from issuing requests but non-profit organizations as well. Also, the cap on fees would be eliminated, further increasing the barriers for people wanting to issue requests.

Is there any material difference between a non-profit asking and people who work for the non-profit asking? Is the maker of the request made public or something?

It sounds like the organizations thing might just be to stop foreign nationals using that as a workaround.
