Maybe if you already use the things that they are pushing on you, you won't notice anything. But every time I've updated my work laptop Apple have tried to make me opt-in to Siri after restarting with the new update -- they even add the obnoxious Siri button back to the touch bar even though I've removed it several times.
I neither use Safari on the Mac nor any of their cloud offerings. No nagging. No ads. No promotions. The only thing I had to say no to is telemetry and Siri on the last major version upgrade (the dialog was already set to my previous choices).
