It costs $75 for an individual license, not really in the spirit of UNIX
UNIX was created for ATT to sell more telephone service, and then later sold and licensed to other companies to likewise improve their internal computer usage. UNIX was not created to be zero cost. Apparently a commercial license for UNIX cost $20k at the time (or $150 for universities/educational institutions).
edit: IMHO $75 one time is a fair price for a premium font. Designers regularly pay $300 or more for typefaces they use in their work. There are monthly subscriptions to font foundries that cost more too.
From where did you get this idea? Citation needed.
I can't find an article for it, but I remember reading somewhere that AT&T's extravagant research budget and forays outside of telecommunications were partially a defensive maneuver: AT&T was aware that the US government could dismantle its monopoly at any moment, and invested heavily in R&D as a token of good faith.
