And it was an antitrust action that unlocked a lot of that value. The consent decree required Bell Labs to license its patents (e.g. transistors) for reasonable royalties. The same consent decree also forbid AT&T from entering new industries like computing. So after they built UNIX, they sold the source code 'as-is' to universities for $200 ($20k for businesses).
Ask anyone who was alive back then and they will tell you stories of how legendarily awful AT&T was to deal with. My father has told me several. The antitrust action made things better for regular people by allowing them to do things like buy their own handsets or haggle over price.
