Which argument? The one dismissing all arguments about IP on the grounds that some software engineers are pirates?
That argument is not only unpersuasive, it does a disservice to the rest of the post and weakens its contribution by making you as the author come off as willfully inflammatory and intentionally blind to nuance, which does the opposite of breaking the unproductive equilibrium. It feeds the sense that those in the skeptics camp have that AI adopters are intellectually unserious.
I know that you know that the law and ethics of IP are complicated, that the "profession" is diverse and can't be lumped into a cohesive unit for summary dismissal, and that there are entirely coherent ethical stances that would call for both piracy in some circumstances and condemnation of IP theft in others. I've seen enough of your work to know that dismissing all that nuance with a flippant call to "shove this concern up your ass" is beneath you.
