A Bill Of Rights
I found this article on EFF to be a very concise summary of many of the issues I've written (and often talked about) in the past, pertaining to the freedom to use the devices you have paid for and own as you see fit, and the increasingly worrying trend of manufacturer lockdowns that largely define what you can and cannot do with them. While Apple with its popular iOS may be the most well-known (and most successful) ambassador of the lock-down platform, the trend has been on the radar well before Apple managed to escape the threat of extinction in the late 1990s; Microsoft, with Windows RT and the Secure Boot flag in UEFI only manages to actually implement all those technologies they initially developed, studied and proposed more than ten years ago with Palladium/TCPA.
The cat is still out of the box, but technology ages quickly and the threat is quite real: a combination of a cloud abused by the Valley oligopoly, lack of the computing storage ubiquity and locked down devices would be a nightmare scenario that would strip the computer of its fundamental differentiating quality from appliances of yore: its malleability, the power derived from its programmability and its ability to solve countless problems, to achieve infinite different tasks and not perform a single function, as manufacturers would most likely want.
