Please show me where I said I ONLY use Apple products. I'll wait. Moving on from the silly comments, As many people who've been using Apple for decades, leaving the walled garden is very difficult. Plus, Apple has a reputation for not playing nice with other platforms. So, some people might have a iPhone but work on Windows at work. If they lose their phone or are restricted from using their phone while at work, then you've just created a significant pain point and possible security friction as some people may start to write down passwords.
