I am struggling to see how this analogy is relevant. It seems more like a knee jerk to the use of "force" in the headline. TFA seems to be talking about a potential way to _generate revenue_ through side channels that are deemed valuable by the users. This is clearly different from "demand the user to pay for it" as the analogy would imply.
Open source contributors don't come unsolicited to "clean the users' windshields". They just write stuff that they find useful and the inherent value of that work attracts other developers as much as users. And then the whole thing grows too large to maintain without serious money.
