I don't think I'm all that opposed to competition in this space. Yubico has a virtual monopoly on high-quality Fido U2F keys at the moment. Google is a giant admittedly, and could crush Yubico overtime though. Not sure if this is just a cheaply made Feitian Key though rebranded for Google Cloud, or if it is a new product in itself.

However, I've heard that Google is kind of going on a tangent with its own U2F implementations, emphasizing an old-school implementation instead of the Web Authentication Standard that's pushed by the W3C. Google's entry and dominance in the security key industry could be detrimental overtime by limiting the actual implementation of FIDO U2F, or it could push security keys into the mainstream too, and with that, open the floodgates for supply.
