Why is this a question? What it boils down to is simply this. People cheating people means all hell breaks loose. People cheating computers doesn't effect anything except the experience of beating set task to its full. Computers don't cry and complain.

Cheating in PvP affects other people; cheesing raids doesn't. Apart from upsetting people with a snowflake complex, of course. I much prefer doing raids properly - cheesing them is, for the most part, tediously boring.
