FLOSS is a textbook example of economic activity that generates positive externalities. Yes, those externalities are of outsized value to corporate giants, but that’s not a bad thing unto itself.

Rather, I think this is, again, a textbook example of what governments and taxation is for — tax the people taking advantage of the externalities, to pay the people producing them.

Open Source (as opposed to Free Software) was intended to be friendly to business and early FOSS fans pushed for corporate adoption for all they were worth. It's a classic "leopards ate my face" moment that somehow took a couple of decades for the punchline to land: "'I never thought capitalists would exploit MY open source,' sobs developer who advocated for the Businesses Exploiting Open Source movement."
