It would not shock me to see some Amazon IoT gadgets have a TI CC1101 chip inside them (what powers the flipper). It's a very common line of chips for wireless comms on sub-ghz bands.
What would be hilarious is a firmware mod for an Echo or something that turns it into a Flipper...
The Flipper Zero is not about the hardware, all of it is literally off-the-shelf stuff.
It's about the software inside + the community around it.
