I believe the point was these companies benefited greatly and specifically from basic research funded by the government: they should therefore "give back" in kind (vs simply contributing to the tax base and relying on a government to figure out what to fund). The reality is these companies care only about shareholder value, and the current US administration has been terminating grants and cutting funding in basic research. I think it's fair to question, in this environment, what these companies' ethical responsibilities really should be.
