If the system relies on integrity, it will fail. If it relies on shame or moral obligation it will fail. There is a reason on the other side of the fence they couldn't root out piracy until they started providing more convenient (but more expensive) alternatives. If you rely on people feeling "obligated" to pay, they either won't pay anyway or won't use the software. That's not a viable option.
So you're left with the other option. Whether one agrees that FOSS is "broken" or not, the only way to make the system sustainable is... well, to make it sustainable. If that means enacting political change, then that's where the effort should go.
Yeah, for sure. I'm just wary that the line between cynicism and defeatism is thin, and defeatism leads to conformism.
