Well I wish this was the case as well. Most developers writing apps are making them a for a company/employer. Try to telling whoever you work for to ignore iOS for moral/ethical reasons. Companies and even independent devs are just trying to make money. Also if a company or dev says no I am not going to jump through your crazy hoops Apple. Apple is not going to care some other company or dev will. It won't really effect apples bottom line much if at all. Entities publishing apps are a disparate group there is no coordination, Apple a single entity that also has the private cryptographic keys for these horribly locked down devices. So apple basically holds all the cards here when dealing with a non-coordinated of people and companies making apps. The only way Apple would care is you could some how basically get almost everyone to boycott making Apple apps.

It also does not help that most users don't understand that the way the device is locked down really limits their ability to truly own their device. Even those that have some understanding of how apple is basically infringing on the owners right of exclusion by not letting them load their own boot ROM and/or OS keys to sign OSes/apps themselves or sideload. Some how think that this being prevented is a good thing cause "security". Like what? You can't trust yourself, but will trust Apple okay then...

A boycott here would be strange. This is a type of app that Apple did not support until recently, and I’m sure doesn’t really want to support. Finally they were strong armed into allowing it… I’m not sure what a boycott would prove, or to whom. Apple would just use it to argue against further opening up their App Store—saying “look, the developers don’t want to be here anyway”. The developers themselves wouldn’t lose out, since until recently it wasn’t even an option. I guess the only people who would even mind would be users who would want to run emulators on their iOS devices.

It’s a commonly repeated point that Apple needs developers, but it’s even more true to say that developers need Apple’s users.

Isn’t that sort of what we’re seeing on VisionOS, where Netflix and YouTube are both like “Nah, we’ll wait…”?

Meh that won't happen until there are decent alternatives out there. Google's Android isn't such an alternative, and other options aren't supported by all the services people need to use.
