Linux would never had taken off without the contributions of companies like IBM, Intel, Oracle, SGI, Cray,....

Which aren't properly any FOSS angels, when we examine their product portfolio.

Actually IBM is the king of patent submissions.

Sure, but it probably also wouldn't have taken off without its license either.

In that I agree, only because it is a copyleft license.
