Indeed.. An awful lot of people seem to think an exploit is anything they don't like. You're doing "x" and I don't like "x". You're exploiting!
People continued calling PL an exploit even after Yoshi-P stated he had no problem with it.
If anything, it's a great demonstration of how some people are so determined to cling to their own personal views, that they'll ignore contrary info even from an official source.
I love how people are now playing it off as saying "Oh, it's an exploit. SE just won't call it one". -eyeroll-
