You're forgetting that a majority of the companies implementing these policies are doing so at the behest of the federal government. You think Google doesn't do business with the US government, who does business with drug manufacturers? Private company? on PAPER, sure...
Government mandating private business to inject their workers every 6 months to save face (and $$$) for the "vaccine" manufacturers is fascist and anti-human. Thankfully the over-arching Biden mandate probably won't go anywhere, but large companies such as Google are doing this as a political and financial move. NOT FOR HEALTH
When politics and money make it necessary for companies to coerce people into injections every 6 months, a constantly shifting definition of "vaccinated", then things should be re-evaluated. And if you believe in this garbage you should honestly re-evaluate your concept of liberty.
