That is a gross overstatement. As someone who works for a pre-IPO startup and been in the bay in various startups for a number of years, I'd hazard that only 5-10% of the engineers had YubiKey, let alone "work in tech".
Whether or not we _should_ is another question.
But yes in e.g. banking the security systems had been created long before there where really good USB based security keys so it's probably most times actual smartcards.
But then it also turned out that many smartcatd drivers are just REALY bad and complex potentially making your system more vulnerable so I can totally see companies switching away from them.
I would link to a feature matrix, but Yubico makes it impossible to find one (although I know it exists).
Edit: found one https://www.yubico.com/products/compare-products-series/
If only people were allowed to bring their own Yubikey for U2F and OTP, then they wouldn’t have to wait on whatever official procurement processes are in place from their approved suppliers.
