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.
UNIX was created with no purpose in mind other than to get some MULTICS-like functionality out of an old machine and not worry about design-by-committee.
The first real use for it was document processing and it took off from there. Never was a telecom system ever at AT&T AFAIK and didn’t do networking until much later.
There were no “teams” there, just someone would see what someone else was working on and dive in to help. Stick a bunch of smart people in a building and see what comes out.
R&D at Bell Labs was to play with ideas first and then find an application. That’s how we got the transistor and UNIX, and waaaay more things that never saw the light of day.
That mode of R&D is dead now. It was dying even as UNIX was being developed, and they got management cover. The use for speeding up technical documentation really was the first business value justification. That was also how they managed to get the PDP-11 and how C got created for the port.
