Similar to another commenter’s note about Raspberry Pi, this seems like an argument that an well-supported, and ideally open, OS is the way to go for devices. Android comes to mind, even iOS would be unlikely to leave customers in a lurch.
Yeah, if only there was a well-supported open-source OS that is generally regarded as reasonably secure and has been ported to pretty much everything under the sun. It would be nice if it ran the GNU userland for easy development and had a fast and portable kernel.
Since the Revolv products themselves already run such an OS it might just be a matter of popping a root shell, curling a dropbear, and killing the update daemon.
