> If you’re required to install software on your phone for work then your employer should be legally required to pay for your phone. And then if you want your own phone you pay for it yourself. And if your employers IT team lets corporate devices get malware that’s on them. This is a weird edge case to get hung up on.

I'll support any sideloading regulation that includes all of these protections. As it stands this is only a law in some countries/regions and certainly not something everyone will be protected by if they happen to be outside of EU (and maybe US) jurisdiction.
