from a naive standpoint i would call apple's point hypocrit, from a more cynical I'd call it an attack on the business of a competitor (while using the services provided by the same to empower their own products).
Example : Safari on iOS and OSX defaults to Google for the search engine and Apple collects billions of dollars from Google to make it easy for you to sell your data to Google - the very thing Cook is trying to sell you as evil! Same goes for FB, Twitter and Bing.
Also Apple collects a great deal of data just like others and it is not provably different than others unless you insert irrational faith into the equation.
Umm, what? Did you really not know you can search with Bing on Android? You can also not choose to add a Google account and instead use alternative app store on any Android phone by the way. People user Google services because they like them and find value in them. No different than on ios.
i think the article very clearly states some valid arguments and the user in the parent comment fails to provide arguments countering those.
