I'm not sure you finished the piece. The author says this:
Luckily, Twitter has an amazing feature that will
instantly remove negativity from your stream. It's
called UNFOLLOWING. The next time something feels a
bit too snarky: Unfollow that user. Before you know
it, you'll have a really nice place where people have
interesting and quirky conversations.
So you seem to be agreeing with him, not disagreeing.
To me the larger take-away points are these:
1. We should not idolize these people.
2. We should try to be better ourselves.
