I definitely respect Commtech's opinion on this one. This is not a "right or wrong" argument. But I don't think people are being hypocrites in most cases because I don't think folks make apples to apples comparisons in the examples you are bringing up. You are only a hypocrite if you violate a rule or norm that you yourself hold. If you make a distinction between different, albeit similar behaviors, then this isn't hypocrisy IMO.
One thing that factors into my own opinion on this is the degree to which these behaviors affect the community broadly. Because of Q's actions, Trevor Grove essentially left the board. Also, Rainman has drastically changed his policies for selling heads, and Denny Kim has also had his policies affected apparently. Adam was probably also affected by this, though he claims to have stopped doing work because he didn't feel he had the right to. This isn't an argument that A is ethical and B isn't, but rather that some actions don't contribute to boardies having less cool stuff, and custom artists feeling less comfortable on the board, while others do. I think the Darklord weighs these kind of factors heavily.
Having said that, I think Robbie and others who do mods to existing work in order to only complement pieces you could buy officially or from original creators are completely cool in the sense that they only enhance the likelihood that someone is going to be buying an original product. One of the guidelines for what is unacceptable selling behavior on the board is when a recast might directly impact the ability for an original creator (be it Hot Toys, Grove, Rainman, etc.) to make profit from it. That's why straight up Medi recasts aren't allowed on the board. There's little to no chance a 1/4 scale Indy will be purchased with the sole intent of trying to modify that head to be 1/6 scale, and there's no real chance of someone buying an extra Batman figure to carve out the mouth to fit in a cowl. So, those are more acceptable than someone who makes a straight up recast, and thus deprives real artists like Rainman, Beto, Denny Kim, and Trevor Grove of the fruits of their labor.
In full disclosure, my own beef with Q stems mostly from some personal conversations where he came off as very disingenuous and deceitful. He thought I was someone who didn't know better about something and was wrong, and when people are blatantly dishonest with me like that it really bothers me.
