My concern is around embedded type systems and maybe even the 'trusted' frameworks etc. I _think_ I can see a completely opensource system that the end user cannot modify _in any way_. Which kinda defeats the point (to me) of opensource. This 5 minute design undoubtedly has flaws but it shows a direction: A basically standard 'De11' PC with some flash. A Tivoised boot system so only signed kernels boot. A modified kernel that only runs (FOSS) executables whose signed hash lives in the flash. Do we (you) _want_ to prevent this? Do we trust in 'the market' to prevent this? Do we use license tools?
