It is probably more pricing of different products in their selection. If you just need U2F you can get their security keys [0] for 20$. 18$ if you order 50, and probably even cheaper if you ask for > 1000 (i.e. an entreprise customer).

And 5$ manufacturing for 20$ resale is pretty much a standard ratio in consumer goods. I would also argue that a competitor would have a hard time making those at only 5$, making it harder to compete based on price alone.
