Why is it considered an abuse?

Here is a description on what service pastebin provides: "Pastebin.com is the number one paste tool since 2002. Pastebin is a website where you can store text online for a set period of time."

It doesn't make pastebin abused just because some internet individual thinks it is only for interesting source code.

It's possibly abuse because it's possibly used for illegal activities.

"just because some internet individual"

Your condescending tone implies undisclosed motives. I might be wrong, feel free to correct me.

Judging by the comments on the linked article, I'd say quite a few black-hats and crackers/etc are upset he's bringing this to light for those of us who were unaware.
