Yeah I am sure too, my last company used google apps and I didn't want to use my personal number for google, but they forced me to insert a number in order to use 2FA, so I had to ask for a work SIM just so that google would STFU, it was said to be a backup method for google authenticator, f*uck google

Companies using google apps, keep in mind, you pay money for a service but if there's google involved, you're still a product, just avoid it
