Guys from Trezor are such idiots, right now other wallets won't touch this shit anymore with this license, integrating Trezor for Armory, Multibit, Electrum, etc...
One reason I held off buying a Trezor was the 100% closed transaction server used for myTrezor.com, there's just no way I'd be happy with that. If this new licence prevents the developers of p2p clients from integrating the code needed to drive the Trezor device, well, it just makes this even more tragic.
Only a kid will get angry like this after his toys are borrowed by some other kid.
"look, you can take a look at my toys but don't touch them"
It does look like an emotional reaction from the Trezor team. They would have been better off trying to use their brains, instead of relying on intimidation.
