Now if someone was bringing up Apple to draw similarities between what they do and what Google does, or to make distinctions, I can see how that would enrich people's understanding of the issue.
But that's not what happened in the comment in question.
If we're not careful, this whole thread will be a pissing contest between Google and Apple fans. And we'll forget what's really important (the fact that companies are trying to claim the open web as their own territory)
People saying "what about X" is useful for adding perspective.
Furthermore, adding "ism" to normal conversational mechanics just because you think it's "a bad thing" is pretty cringe.
What I'm saying is that each normal conversational mechanic doesn't deserve an "ism" just because you think it's "a bad thing".
It's perfectly normal to add perspective by saying "what about X" in a conversation, which is what this site is here for. This is not a structured debate for crying out loud! People can make your comment disappear without even having to prove anything!
