True. Imagine if John Deere was a monopoly and insisted upon 30% of all crops that are harvested using their machines. Or if AT&T insisted on 30% cut of all sales performed on their phone network. Or an innovative prosthetic developed by a medical company insisted on 30% of income generated when using the prosthetic. Should this be allowed and does this damage the economy in general allowing for these companies to suck money out of transactions when using their devices?
