Don't kid yourselves, regardless of all your ideals open source only works because it's free from a monetary perspective.
Companies work on patches to Linux or other software because it primarily benefits themselves, and they only use Linux because it's free. Companies create hardware on Linux because it's free. They can manufacturer cheap devices and people will buy them because they were low cost primarily because of the use of FOSS software.
Nearly all of FOSS is funded by corporations whether you like it or not, for the reasons you want to hear or not. The only thing that drives people is money.
