I really dislike this point of view.
1 - we're all going to suffer because meta are scum. It's not "all application developers", it's "exactly who you assumed it would be", and also too, "exactly the same scum who've spent the last 10 years working around privacy controls any possible way they can and deliberately obfuscating the choices people make around their privacy." The people who made pervert glasses and did covert web-to-app tracking by opening local ports [1] and bought sketchy spyware to track everything you did and scurried away from the light the second someone asked about it [2], [3]. And on and on and on.
Spotify has long asked for it and... they use it to copy my local mp3s onto my phone so I can listen to them away from my computer. It's awesome.
This doesn't mean that Apple isn't champing at the bit to use Meta as an excuse to screw all software developers. If Apple cared about their users, they'd do something like revoke Meta's software keys and leave responsible developers alone. Alas, Apple will obviously exploit this too :(

Apple considers a user deliberately delegating access to their data to any program not controlled by Apple to be a serious problem that must be corrected.
Application developers are not making the user experience worse, Apple is.
