The thought pops into my head that free/open source, and by extension software in general, shares many characteristics with “creative” industries such as publishing or music
The foundation of these industries is unpaid passion labour that’s treated as disposable.
@baldur There's an analogue in the games industry, where the passion-project nature of the work leads to incredible overwork exploitation (it's not unpaid in this case, however, but can be relatively very low)
