So much of this thread boils down to cheating vs breaking the rules where breaking the rules = tos.

Some distinguish between cheating and rule breaking and others do not.

Some are willing to break rules they consider minor for whatever reason and do not consider that cheating. They then have a different feeling for what exactly constitutes cheating.

For myself I have a personal ethical issue with breaking the rules of a game. Note I am only speaking for myself here. I won't do it to the best of my ability. The rules say NO 3rd party programs. As such I refuse to use any at all.

As for what other people do. I can't know what you have on your computer unless you point it out to me. The guy I witnessed harassing a newbie in a low dungeon with actual DPS numbers? Yeah I reported him for both harassment and parsing. The guy claiming thanks to his addon I was naked and then making very lewd and offensive advances to me (I was on a lala at the time and what he was suggesting is flat illegal in many countries)? Yeah I reported him. I don't go hunting for violations. If they are shoved in my face however, I will report them. Otherwise I really don't care what you are running on your machine for your use.

I do have one exemption: I want BOTS gone from the game. I will report them every time I see them.
