Here I write little posts which aren't lenghty enough to be made into a post:
Tools
We should know how our tools work and how to repair them (though only partially because otherwise would be impossible). One shouldn't be sold seat heating subscription in his car which he has already paid for. One shouldn't be hindered by a proprietary screw or socket.
I hope one day I can express my thoughts concerning this matter clearly and show how it affects our freedom and capabilities to use the said tool.
