It's not as clear as it seems. For example, he mentioned that if they decided to terminate all accounts that use third party software, you'd have taken that risk if you decided to use ACT. This is never going to happen and is basically no risk. First he explains later that despite realizing people have asked him to be stricter on ToS, they're never going to scan your computer for third party software. Secondly it would result in a sizable loss of subs. He even admitted it's a complicated grey area.
The only clear thing was that he does not want dps bullying. That's simple enough, whether you use a parser or not, don't harass other players.
