You should not be surprised. If you look at most of the jobs in the careers page for example [0], they mention the need for "Experience with framework-level customization of AOSP" and that the app is in "Flutter".
So this was immediately obvious that it was running Android. It is just that this was a nice and perfectly packaged scam, but not as expensive scam like the Humane AI Pin.
and yes. Humane is also using Android for their AI Pin devices. Unsurprisingly. [1]
The kind of SoC that you would put into something like this often only has official support for Android, too. If you're making any kind of mobile thing then Android is almost certainly the path of least resistance nowadays.
The Playstation Portal is another good example, it's a single-purpose device just for streaming games from a PS5 but it runs full blown Android, locked down so you can't use it for anything else.
So? A scam is a scheme to profit by using dishonesty. Making something poorly, or cheaply, or not to anyone's liking has absolutely no bearing whatsoever as to whether something is a scam.
Things can be (and many things are) gimmicky, early development, cheaply made, or made to someone else's preferences in a completely honest way. This is that.
That’s not a scam, either. They’re not being dishonest about what the hardware really is. They’re probably at least being unrealistically optimistic about the future software, though.
