Did you even read the article?
Yes.
You are the one that asserted it was BYOD.
No, iOS covers private use, BYOD, Corporate owners, and government owners of devices. Private individuals, and even some corporations want the ability to side load. If Apple nukes the option to sideload, that affects BYOD users and private users. So yes, this is part of the BYOD scenario. And for that matter many governments and government departments support BYOD. You are the one that says it is BS for an enterprise to want to control what their users install on their equipment. You turn what should be an noncontroversial topic as an anti-Apple screed.
That's actually not something I said, but you seem to think I did. Did you read what I posted? The fact that this is a news article and wasn't someone simply sidling up to an Apple exec to say "hey, if you can't support sane device management, we can't keep purchasing Apple phones" to the extent they purchase them at all tells me this isn't about solving the technical problem and Apple is just trying to get the EU to back off of their position so they don't have to impelement a change that they don't want to because it affects their bottom line.
Please cite the setting in iOS that allows the employer to do that currently. I'll wait. Oh, there is none because it does not exist yet. If only people who wanted that setting should say something. Oh, that is exactly what they are doing now.
That's correct. You can't disable a non-existent setting using a device policy management system. This article presents as "see sideloading is iNsEcUrE!" - so you shouldn't support it, not "Hey, Apple doesn't support proper device management" - do you see the difference? One is spreading FUD to try to continue to drive profits, the other one just tries to fix a technical problem. But crucially, we don't know that Apple isn't going to give this device management capability to corporate/government customers on their as-yet-unreleased feature.
