The essence of cyberpunk is anti-corporatism. All the other principles follow from this. Technology wielded by a large company must be combated, by the police (hence Ghost in the Shell) or by hackers (hence The Matrix). A corporation is a quasi-governmental economic organization — a power structure that coalesces in favor of profit.

Personally, I am not inherently opposed to market operations. But I am opposed to power beyond oversight, which corporations tend to aggregate for themselves. Why wouldn’t they? We need to provide them with alternative incentives — selfish motivation is key. The system must be constructed so that personal benefit is good for others as well.
