I would say that it is a new trend for pick-up instructors to distance themselves from the pick-up industry mostly for marketing purposes. I think it's mostly semantics and at the end of the day, you're just fearing the phrase "pickup industries" focuses too much on the negative and not enough about the positives.
On the otherhand, as someone who's spent fair bit of time observing pickup companies, I will say that your marketing page seems very reasonable and not full of false promises common on most PU sites.
