What they would prefer is that you continue to offer up your unpaid labor that they can then use to build fortunes upon. It is no accident that businesses are happy to encourage "open source" so long as that means "make us stuff we can use to make money with without paying you a dime". "Open source" has never meant you couldn't charge for your work or otherwise impose a noncommercial use restriction on it, though the OSI and its pro-corporate partisans have gone to great lengths to claim otherwise (much like they like to pretend the invented the term and/or the concept).
At the end of the day I don't work for free, and I'm pretty sure you don't either, so if you want to get paid for what you do then make them pay you. The End. Full stop. HAND. TYVFM. FOAD. Etc. Ad nauseum. Anyone who says otherwise should not be engaged but simply told to get lost... because if they want Free Shit then they know where to find it.
