Around here a consulting company has specialised in this (you don't get an interview unless you have an autism spectrum diagnosis) and last I heard it wasn't at all sad:

Some autistic people with correct skills were paid good money to do things they really liked well like iron out rare bugs in financial services etc.

So not only to fill some quota and not taken advantage of. Oh, and said company made good money IIRC.
