Yes and no.

There were really 2 sides to the original 'tech' industry: military and consumer. The military side was always about profit, because it was just an extension of the already extant WW2 military industrial complex (and frankly, IBM falls here despite their mainframes being largely used in civilian businesses).

But the consumer side that really grew out of universities into early gaming, internet, and consumer electronics tech, was very heavily driven by design and garage-start tinkerers. That's not to say no one wanted to make money, but it wasn't MBA-bro-driven back then.

Gaming got very corporate very quickly. Atari sold itself to Warner in 1976. Magnavox was a defense contractor. I don't have to tell you about Fairchild or Mattel or the Connecticut Leather Company. On the arcade side, Bally, Midway, and Williams had been making pinball machines for decades.

I'll grant you that there were a lot of "garage-start tinkerers" on the home-computer software side.
