That open letter had nothing to do open source (i.e libre) software as we understand the term today. It was simply asking hobbyists to pay for Altair BASIC which was not distributed under an open source license. I don't see how that's anything but reasonable unless you take the position that all software ought to be open source regardless the creators wishes.
