It's a comment on their monopoly position and how they can make it difficult at any point for a third party to run their business/app. Apple doesn't need to jump through these hurdles, but they can be placed in front of anyone else randomly, disrupting their business and income and at the very least, creating a worse user experience for those apps.

The article states that the alert had to be changed from:

"The camera will be used to take photographs"

to

"The camera will be used to take photographs for the app that you just downloaded to take photographs for."

"Spotify, why would you like to play audio? Please notify the users that you are using the speakers to play the audio for the app they just downloaded to play audio."

If they make using third party apps a little more scary, a little more dense, consistently, people will slowly gravitate to Apple's first party apps. You can see a similar pattern for MacOS where more and more restrictions are added to opening apps downloaded from outside the App Store.
