GPL-ers think that companies keep secret a lot more than they do. It's mainly just secret sauce and added value. IBM, Intel, Juniper, iXSystems all drive FreeBSD development.
If you look at most of the biggest/most useful libraries for Python and other languages the heavy lifters are all BSD/MIT/Apache (or similar): Numpy, Scipy, sklearn, Plotly, matplotlib, Tensorflow. Because of their use as building blocks in larger tooling I feel the non-GPL is important.
I have occasionally found an edge case where I knew I had a secret sauce and intentionally made it GPLv3, but that is the exception.
