I don't think you could classify changing parameters as modifying software or firmware. Changing parameters is something I have been doing for many years on all of my various RC craft to enhance and personalise how they respond, etc. Should we not have that same level of customisation on something I purchased? I can modify my car in any way I seem fit. Some might say having the capability to go over 300km/h is crazy however when using it also on the track, I would be able to use this capability. It is up to the police to make sure I am doing the right thing on the streets (and common sense). My computer I can modify in any way I chose. I actually cant think of anything I have purchased as a consumer (not commercial) that I have the right to change as I see fit as long as I am licensed to do so(240V equipment as an example of where a license is required). Am I missing something???
