Previously, each developer had to do one or more of:

* use TestFlight for centralized distribution of pre-release apps, through Apple (with some lighter-touch app review involved), or

* use enterprise signing (which requires enrolling in a more expensive program and jumping through some corporate hoops, with your apps subject to deactivation if you abuse it) to install on an unrestricted number of devices theoretically owned by your company, or

* whitelist a pretty low number of specific iOS devices to install arbitrary apps onto — I think that limit is still 100 devices per year, per developer account

This sounds like it removes the whitelisting requirement from the third option. Hope it's enough friction to prevent the worst aspects of sideloading from taking hold.

If this removes the whitelisting requirement, that would be awesome—but I’m very much not holding my breath. My pessimistic guess would be nothing else changes, just a bit of extra fiction.

It’s 100 devices per type per dev account, so 100 iPhones, 100 iPads, 100 Apple TVs, etc
