Apple will help advertisers and spammers target you.
Russian corporations will help thugs, racketeers and corrupt police target you and government will sell your data on the black market.
So no, it’s a question of personal security, not of simple annoyance.
I would much prefered if Apple left Russian market and we had to import iPhones via backchannels. That’s how bad privacy situation here is.
There is no nefarious plot. Apple just gave us and our data to criminals to keep small insignificant market.
