Amstrad's aim is to lock down the device. The use of GPL software in a
device sold at a subsidised price was an error on their part since the
GPL allows me to alter the E3 and remove the part that earns Amstrad
post-sales revenue whilst maintaining functionality. Given Amstrad's
lack of compliance knowledge when I initially contacted them, and that
they never included the license in the package, I think they were poorly
advised by MontaVista and didn't do sufficient research themselves.
To summarise the concern expressed privately to me: it's that 1,000
units can be picked up by some commercial outfit, e.g. from Russia,
taken back there, and used to some completely end that earns Amstrad no
Having put the key system in place, adding to their list of GPL
violations, I doubt they'll release a downgrade that lets us circumvent
