you're getting no traction with your argument because you're grossly overreaching with it.

not having yubikey support is obviously not "very very scary" since most people (even on hn) don't have yubikeys and we don't run around with our tails between our legs.

many reasons can lead to not supporting yubikey yet, including the simplest, which is that it's lower on the priority list for a resource-constrained organization. or another likely explanation: yubikey has unsolved ux issues that keep it a niche product (for now), so demand simply isn't there.

this seems to be an important issue for you, so if you want to effect change, then you need to come across as well-reasoned, not fud-filled. (edit: and don't let perfect be the enemy of good.)
