The seems to be worrying about a bait and switch scenario, or a embrace, extend, extinguish play.
RMS is in it for the long view, that some critical issue can't be resolved because it needs something that has been lost years before thanks to some economic entity going tits up.
What set him on his path was the university getting a new printer thanks to a clueless department head accepting a "good" deal from a vendor. With the old printer RMS could access the source of the drivers, and had added a small bit of code that would put a message to whoever was doing a printing when the thing ran out of paper. The new printer driver only came in binary blob form.
Similarly, there are university labs out there using rickety old 486s etc to run their test rigs. This because a vital sensor driver can't work on newer hardware, and the supplier has long since caved in or discontinued the product. And if they want to replace the sensor they will have to run a long list of basic experiments to make sure the old and new results line up. And that will set the lab back perhaps a year.
