Yes, understandably it's a slippery slope in the regards that it could be used in that way. However, the argument that "anyone could do the same thing in enough time" with an abacus and their battle log is a non-sequitor. I could very well do the same thing for the performance system with a midi device such as a keyboard attached to my PC, and people already are.
In terms of being "one step away" from those bots, ACT is also in the same boat as in order to do what it does it needs to access the memory locations that the game is running in to read that log which is a direct, unequivocal hack far closer to the bots teleportation hacking than a program that automates valid keypresses is.
The devs have made the precedent in their statements on such things that intent matters. What you are doing with a tool matters more than what the tool is actually doing. If you're not hurting anyone with what you're doing then just don't advertise it.
