I don't really understanding what you are saying.
What I'm saying is that a SIM card is a computer designed to operate in a way that I find philosophically repugnant and deleterious to individual rights. As a computer, it both stores and processes data, but is specifically designed to exist as a black box that locks out the owner and frustrate attempts for the owner to exert control over how or what data is processed on their device. Thus, it violates the principles of open computing in a fundamental, and very dangerous, way. The technology is specifically anti-consumer, anti-citizen, and anti-property-owner. SIM cards are not there for your benefit, and do not serve your interests. They are designed and built specifically to disempower you, their owner and operator.
I don't like, and do my best to avoid using, technology like that. You should, too! Normalizing this kind of technology ultimately causes real harm to real people. Industry and government have a deep and abiding desire to make us all into passive consumers rather than empowered and active users of computers and networks. Technologies like SIM, CableCard, proprietary firmware, etc. are one of the main tools they leverage to accomplish this.
I believe that computer owners should be free and empowered to leverage their property in any way they see fit. Technology should work for, not against, its owner.
