Intellectual property is a capitalist concept and its abolition is the clear leftist position
The purpose of intellectual property is to take something non-physical and turn it into private property. It is a means of creating passive income from labor, just like any other form of private property. It is a tool for privatizing the means of production of culture and innovation. Intellectual property uses state violence to prevent the free spread of ideas and experiences.
IP is a purely capitalistic concept - invented under capitalism, written by capitalists, for the benefit of capitalists. In practice, it only benefits the wealthy at the expense of the working class. There are countless examples of poor people suing big corporations for violating copyright, only for them to lose the case. On the flip side, extremely popular parts of our shared culture are guarded and gate-kept, preventing the poor from taking part in their evolution and reproduction. This has a deeper effect of all iconoclastic culture that gets too popular eventually coming under the control of capitalists, who co-opt and de-fang it of any revolutionary potential.
IP is incompatible with communism. It is also incompatible with anarchism. These societies would not have the means to enforce it, nor a class of people who could benefit from it.
For generations, the abolition of copyright and intellectual property was a bog-standard leftist position, supported by anyone who called themselves anti-capitalist, communist, anarchist, etc.
Until recently.
The anti-AI movement is utterly and completely in favor of IP - strengthening it, utilizing it to make demands about what algorithms can and cannot do, and using it to justify its moral claims.
The anti-AI movement also often claims to be anti-capitalist or leftist.
Is this a contradiction?
