Article 5.3 of the Digital Markets Act (DMA): “The gatekeeper shall not prevent business users from offering the same products or services to end users through third-party online intermediation services or through their own direct online sales channel at prices or conditions that are different from those offered through the online intermediation services of the gatekeeper.”
Friendly reminder that you can sideload apps without jailbreaking or paying for a dev account using TrollStore, which utilises core trust bugs to bypass/spoof some app validation keys, on a iPhone XR or newer on iOS 14.0 up to 16.6.1. (ANY version for iPhone X and older)

You are both correct. They do stop things that would be ok, on say, a windows machine. For example, intercepting text messages at the system level. It prevents a lot of mischief but also stops legitimate software.
But we can already look at the Android market for guidance on what will happen. Few Android users venture out of the official store. It will take a large company with must-have apps to get people to go to another marketplace. Like Steam, Epic, or Facebook. Companies that either want to keep their cut or want to collect data to sell. This will likely not matter at all for small developers. They don’t have the clout.
