Personal computers are perceived as the last vestige of this sort of freedom in a consumer product, hence the outrage. None of those other examples are sold with the intention of the user changing the system in a way unexpected by the vendor. PCs are supposed to be open-ended, and for this you typically pay more for the hardware capability than a product which serves as a gateway into a walled-garden ecosystem (phones, gaming consoles, etc.)
