Last time I checked, which was more than 5 years ago, non-corporation contributions to Linux amounted to less than 20% (with Greg H. pointing out that they needed to make life easier for those not-payed contributors).

This means among others that Linux is a Corporate based project and caters to those corporations with a leverage of at least 4/1 for closed binaries with GPL and contributors' voice compensating for the other side.

In the end this is what we have for better or worse.
