Earlier quoted context omitted.
The changes Apple made were to increase privacy. Content blockers that have access to the page have no network access. A separate process that does can only update the blocking rules. I quite like Ka-block
"The changes Apple made were to increase privacy" Apple gobbles personal data too and processes it and sells it etc. They are simply rather better at looking ... friendly. They really are very good at that.
What I would admit is that Apple is maybe not as motivated to protect your data from unintentional leaking. Without user data, Google would be almost nothing. So they have to be extremely careful to maintain the trust of their users. For Apple (or Microsoft) their business is still sizeable enough with out user data.
