If apple doesn't track you outside of the ecosystem, then that is genuinely a better outcome IMO than the google and facebook status quo. That you DO have an option to stop it entirely, by giving up apple services and products, is also a genuinely better option.
Some people aren't against advertising, analytics, etc in the more limited case like apple has. I don't think it's false advertising for apple to say "we respect your privacy" when they have demonstrated that they respect it better than the other companies in the advertising industry.
Don't let perfect be the enemy of better. It is damnation by faint praise, but that's because the bar is literally on the floor here.
