They're the lesser of two evils. Still an evil, though.
Is that even true? They pulled the plug on mobile ad sales a year or two ago (http://appleinsider.com/articles/16/01/18/after-abandoning-i...), where else would they make advertising revenue?
And in any case, a company who makes 99.9% of their revenue off of non-ad sales is definitely would never be categorized as an advertising company. My grocery store is paid to put crest at eye-level, that doesn't make them an advertising company...
IDFA is still going strong on Apple phones and is likely to continue into iOS 11.
I don't know if they're ads or not but there's also location based app suggestions too.
disclaimer: i'm a googler so glass house throwing stones etc, and of course the scale is way different
