Without making judgement as to how valid that "obligation" is, this is pretty much the stance of RMS. No, it's not the stance of RMS that if you use open source code than you are obliged to produce open source. In fact, he considers it essential to software freedom that someone should be able to obtain a free software program, modify it, use the modification, and keep the modified program to themselves. If you release a program of some sort and don't release the source code to give everyone various freedoms, you are perpetrating a great wrong. This is the stance of RMS.
