with ladders/bridges and walls/moats i am talking about the existing material reality that has one class (the propertied class) creating unnecessary artificial scarcity (on non-scarce material, i.e. using the intellectual property system) which stops the organic spread of technology and knowledge overall, as it's following the profit motive of capitalism. this article is from a socialist magazine, so it's common to refer to systemic black boxing and alienating/obscuring technology as 'gatekeeping'/'rent-seeking' (creating walls with unaffordable gates (for 99.999% of us)).
