The device belongs to the user. It is fully within the user's legal right to install apps on their phone, even if Apple disgrees with those apps.
If someone ones the phone, it is within their full legal right to do whatever they want with it. No extra fee necessary.
It is instead how the law works.
Apple tried, and failed, to sue people for doing things with the phones that were legally purchased by the individual.
If you install something Apple doesn't like, it is your full legal right to do so. The courts proved this.
And you'd be wrong.
> How can they claim to take privacy seriously if it’s clearly possible for bad actors to get around the rules multiple times!
That's BS. You might as well say: "how can they claim to take security seriously, if it's clearly possible for bad actors to find exploitable bugs in their products multiple times!"
Apple has a tough job, and it won't do it perfectly because no one can. It's bizarre to claim that it's excellent but not perfect performance somehow makes it guilty of the things it's trying to stop.
On top of this you can add the fact that they basically shipped renamed onavo code, which was already banned from the app store, so this is de facto a violation of Apple's rules.
It's in the long term interest of Apple to not be soft on this stuff, it's not symbiotic.
