It's done worse in this area. Biden administration refused contracts with any company that didn't require all in-person employees to get the covid19 vaccine, so the firing extended down to the employees. The courts stopped this when boosters got added to the requirement.

because it is a big fucking risk if the tool you rely on can refuse to function at a critical moment, and the vendor publicly brags about refusing to eliminate such refusals. ta-ta, see you in 3 years.
