@spaceman - Yes Freedom matters. Had they named it "Freedom Software" then there would have been no disambiguity.

@mcnalu - I don't believe it was a runtime bug as I said there were loads of examples at the time of both paid and gratis software (aside from the levels of Freedom). The term "Free" was also known to be the opposite of "Paid" at the time.
Changing names has been done many times in the past, PostgreSQL, Inkscape, Wordpress, MariaDB, LibreOffice, Jenkins, etc. it's part and parcel of how "Free" Software works. RMS himself puts the better name as a reason why "Open Source" was so popular.

@brian - I reported the bug. I leave it up to better minds such as yourself to apply the patch.
