Not rude at all -- it's a good first step though. In my opinion, it does need a bigger payoff at the end -- so close but they posted too soon. They should've also responsibly disclosed the script on github as well (eh, maybe).
Not only is it a good first step, but since the product clearly runs Linux, the author should be able to download all GPL source code from Honeywell. Being able to build the device firmware yourself from source is hugely beneficial to understanding the structure of the firmware and can even help in understanding the behaviour of the device.
If Honeywell aren't providing a GPL archive for the Tuxedo with the kernel and any GPL licensed user-space programs, they are violating the GPL.
I'm not sure the author is aware that the source code for these should be freely available from Honeywell
It's not clear to me that they would need to follow GPL.
Of course. Honeywell can run their own proprietary applications on top of a Linux/GNU system. I didn't mean to imply that you could request the source code to every program running on the device.
However they need to provide the source code for any GPL licensed portions. IIRC they should also provide build scripts so you can create a firmware image yourself.
