As if there would be a difference in motivation between evil corp#1, evil corp#2 and evil corp#3. You can substitute those names with apple, google, microsoft, facebook, amazon, whatever you like. If you think for one minute that Apple is only a fraction better then their competition you're very misguided by apples great marketing.
Honestly, if you think G+ is bad, or Adwords, but the appstore is not (Or iCloud, iwatch, Siri, Amazon Echo, Whatsapp, etc.) you will need to do a reality check.
All of those are very privacy intruding and every company will do it's best to make money of your data. And pretty much all of those services is made to collect as much information as possible about you.
Use Apple or Google or Facebook and store your private data to be datamined and monetized but please don't fall for marketing speech and all that "don't be evil" bullshit every mega corporation is telling you.
