That's likely because Apple is doing the same thing but just lying to you about it. You can't uninstall stock apps because they came on a read-only system image that was signed by your device manufacturer.
This isn’t true. Deleting apps does actually remove that app and usually user data too. Associated system frameworks might stick around because other parts of the OS depend on them.

It is true. Factory reset your iOS device and they will come back. That happens because the app is stored still, Apple just creates a second copy that it deletes when you remove the app.
