The common definition of spam is something that most people consider junk but a few people might use, thus justifying inflicting it upon everyone. Your definition is almost the opposite: something that most people find useful but that you happen not to need. This is an abuse if not outright misuse of the term.
Haha, many people just find it too painful to admit they were ever wrong. So once they say they support a given team, party, church, company they start ignoring all evidence against it.
Interesting how after your original argument (the difference between app and bookmark) was defeated you came up with a new one (percentage of people liking).
I don't think anybody made the claim that no app is spam, only, from what I can tell, that no iOS built-in app is spam. Which is more than lots of Android phones can say about their built-in apps.
Many people enjoy getting political news emailed to them. Many, many people. Yet it infuriates me when it gets forwarded to me because it is--wait for it--spam. It is annoying crap I don't want.
Spam is defined as whether it annoys the receiver, not the sender's intentions. And there's no 'unsubscribe' in iOS.
