Not really, it's called maximizing shareholder value. They can afford a premium over the generic adapters that will be coming out because they have good marketing and a stellar brand name. Same BS the drug companies try.
I don't know of any 'not-for-profit' computer/consumer electronics manufacturers and certainly Apple isn't one.
Ah look the standard Apple apology crew is out in force trying to cover apples pure 100% greed.
It cost them 10-15 cents to make and they turn around and sell them for $10. Apple is abusing its marketing power. Next thing Apple will do is use this to kill off working with all accessories to force everyone to rebuy them.
It is Apple SOP. They use some odd ball connector and do not follow the standard everyone else uses. Apple is just showing its true greed.
