Yes, they do. Who do you think contributes to the Linux kernel everyday, only individual hackers all over the world pushing FL/OSS ? The vast majority of the contributors are big-tech-co affiliated who come from places like Red Hat, Intel, IBM, Novell, Oracle, AMD, Google, and more. Individuals and those not wishing to state their affiliation/place-of-work are only about 18% of the contributors to Linux.
Btw, this is part of the issue some people have with Ubuntu, in that it makes no contributions upstream to the kernel like Red Hat, Novell and others do. A Red Hat Greg DeKoenigsberg even said on OSNews once that "Canonical is a marketing organization masquerading as an engineering organization."[1]
Python's father Guido van Rossum and other core contributor are employed by Google and other big tech companies to work on Python.
Mozilla is mostly by Mozilla people, however it's basically alive because of the funding and ad deals it has with Google. Without that, it couldn't continue.
