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.

Yes, but unfortunately this never happens; and depressingly, I can't imagine it happening.

The open source movement has been exploited.
