This would be more akin to jailbreaking your nintendo switch and installing linux. An IOT platform that's intended to be secure can be tricked into revealing it's key.

Most consumers aren't going to write custom firmware for their lightbulbs.

Of course, I think this exploit is impractical for a lot of cases given how the ESP32 is typically used, but, ymmv.

I didn't have to write Linux to benefit from an open platform. I didn't write openwrt either but benefit hugely from it.

To protect against clones that just install your software.
