It took me a few seconds to figure out that this isn't a "Raspberry" product. I don't know if the "Pi" name is protected but even if it isn't it's pretty misleading to use it.
From 36,000ft, there's perhaps a similarity if you squint a bit, but as soon as you see the product, you know it's not a Raspberry Pi Zero. And that matters even if you don't know what a Raspberry Pi Zero looks like, because you have no frame of reference to confuse this with (everybody who's heard of a Raspberry Pi Zero, knows what it looks like).

To be fair, Raspberry Pi got its idea from BeagleBoard then Beagle Bone along with Arduino, small ARM boards with Linux.
The problem with Clone-Pi series is that none of them are FCC-certified, while Raspberry Pis are.
