Giving the choice is what benefits the employees more: sure if you want more separation that's nice to have the option, but I prefer by far use my own computer

Giving the choice is what benefits the employees more: sure if you want more separation that's nice to have the option, but I prefer by far use my own computer when I'm WFH because it's a beefy desktop. In any case being forced to use a company mandated operating system is a nuisance for productivity… (be it Windows, where productivity is just bad, or MacOs where I need to relearn everything starting from the most basic key bindings …). Also, companies have no control over corporate IP that land on an employee-controlled PC anyway.
