Ah, so you couldn't rebut what I said, so you throw some new stuff into the mess. Okay.
>NitroKey still has WAY less features and capabilities than a Yubikey. They also don’t have a lot of capabilities needed by enterprises.
OATH and legacy Yubikey OTP are both irrelevant nowadays, so by "way less features and capabilities" you mean "missing PIV".
>Some services in enterprise only accept Yubikey.
That's a company-specific decision... and a poor one at that.
YK repeatedly fails.
