I don't necessarily agree with Stokes, and I'm not going to attack your morals. It's not my business if you are willing to "cost a company $1000" in order to save $30. However, I think you should understand that you're incorrect.
Patent law was established to incentivize new technologies, products, and other inventions. It costs a lot in research and development to invent things even as arguably simple as the magsafe adapter. Patent law gives inventors of such innovations a temporary monopoly on their products to provide the inventors an opportunity to recoup the costs of developing them. Without this opportunity product development (not just in technology, but everywhere, including medicine) would move at fraction of what it does today, because no one would put in the money it takes to develop new inventions.
The exclusivity provided by a patent allows inventors to charge whatever they desire for their products and prevent others from using them, but does not force people to buy them. If you don't think it is worth the price Apple charges to buy Apple products, you don't have to. However, it makes no sense for you to claim that they are immoral for charging what they want for technologies they worked hard to develop first, even if it makes you feel better about buying bootleg stuff. If you want to save money and buy bootleg stuff, do it. Tons of very good, moral people do it every day. However, don't be surprised when it doesn't work as well and don't try to convince yourself you're doing it because Apple doesn't deserve the extra $30.
Also, antitrust law was NOT established to prevent companies from charging what they want for their products. Being able to charge what you want is the essence of capitalism. What you're claiming about antitrust law would make it counterproductive with patent law, and thus one of them would be unenforceable. Antitrust law was established in 1890 by the Sherman Act to prevent giant companies from engaging in anticompetitive practices with each other, price fixing with each other, and similar restraints on trade. It's main focus hasn't changed a lot since then.
