The idea of taking Apple seriously on privacy is a bit of bad joke when they block Firefox having ublock origin or implement at least the same for its Safari, and give users full option to install plugins for this browser (even if only from Apple-curated plugin store). It would be trivial for army of Apple devs to create similar blocking, yet they just curate what ads you see based on what they think is maximum acceptable amount & type for users, so no real privacy choice there.
I've heard even comments here on HN about how its actually a good thing to not have this freedom as 'power user'. Can't say I know how to respond to such schizophrenia so I'll pass on that, everybody can make up their own opinion.
Apple - fix this, and I will start taking your PR about security seriously. Till then, I simply can't since its obvious you talk more than actually do where it matters most, the wild unruly Internet of these days.
