there is no intention to lock anybody and anything out of Arduino.
The IDE will always work with anything that shows up as a serial port.
the only difference is that when you plug an Arduino made by Arduino it says "Arduino". It's a nice touch and better user experience.
The source code for what runs inside the 8u2 will be released in the next few days and anybody can build one if they like.
We worked with the amazing dean camera (creator of lufa) so that we could provide more possibilities for Arduino users to create while staying compatible with previous boards.
On the other hand I do feel that Arduino has to provide customers of its own boards some nice extras and this is one of those
The FTDI chip is just a microcontroller running a closed source firmware, this one is 1000% more open source but nobody is bitching at FTDI for not releasing their code.
Personal note (not an official Arduino position) why on earth every time there is a change in Arduino a conspiracy theory has to come up?
What the hell do you think we are? Microsoft?
