I’m slightly late posting about this here but figured I’d do so anyway.
You can see what their anti-repair measures look like at around the 7:50 mark.
With this new iPhone release, they have also stopped shipping their charger ($19), USB charging cable (opting instead for a lightning to USB-C cable), and earbuds ($159+). They have cited environmental concerns as their excuse to force their customers to spend possibly hundreds of dollars extra for products that will be end up being delivered separately.
As some people have hinted or guessed at in this thread, there is a specific software tool you must run on the phone once you replace components like the camera, battery or display. This tool is only made available to Apple and to its certified repair partners. I will leave it to everyone else to discuss the implications of this policy.

Continuing to purchase their products will only encourage this behaviour further. Boycott Apple.
If security is that important then why wouldn’t apple make the phone display a pop-up or splashcreen to the user informing them of the modification, whilst still allowing the phone to be used? There is no need to render the device unusable, just leave the choice up to the user. I think it is much more likely that these measures are taken to monopolise the repair of iPhones and overcharge customers. I think talking about this as a life-threatening problem is quite overdramatic.
