That was my point. The regulation would not come at negligible cost. It is also entirely unreasonable to demand that manufacturers provide the source code for their firmware when all a user may actually want to do is install a different operating system. Some kind of SDK or developer kit with closed-source binaries should be sufficient for this, with the understanding that users would lose access to certain features, such as Apple Pay or Google Pay, as well as some security features relying on the chain of trust.
