It's funny, I buy Apple products specifically so that that I can't side load apps. At work we MDM and
Apple's approach isn't for everyone, but forcing something like side loading simply isn't the right choice for all types of users.
I'm all for encouraging them to be on the right side of Right-to-Repair, labor laws, and environmental best practices. But I left the world of side-loading and customization for the iPhone's tight lockdowns. At first I still couldn't help myself but to jail-break my first iPhone or two, then I stoped that also.
