If a manufacturer were to use the on-board wireless they could be heavily fined. Certification for these boards would cost around $15k, significantly increasing the price of an integrated product.
At least FriendlyElec doesn't pretend to have gotten their boards certified.

Makers largely don't care about import duties to China, or FCC certifications, or manufacturing tools, or barcodes, or Yocto, or secure enclave chips. Just give us the hardware in an easy to use, all in one form factor, with good drivers and support.
I don't get that from their page at all. At minimum, it seems like they're marketing it to "Makers" who are trying to make an actual product, at which point they do have to care.
Haven't used the Neo2 yet. But its predecessor, Nano Pi Neo is $10, has excellent Armbian support, and is on par with a RPi3.
