Pretty sure the vertical is struggle and toil, and the hacker still has to contend with the landlord and the capitalist while also trying to retain some value from the 'hacks' they produce in labor for the vectoralist. Considering the abysmal rate of creative worker unionization in the info space, I think it makes sense. The hack doesn't usually require reproductive labor in the same sense as the previous forms, so it's much more difficult to create labor power under this relation. Software developers are regularly laid off after they deliver working code for example, and the labor can be replaced by coders at much cheaper pay in another country with very little friction.
