I feel that "you only care for the sex scenes" qualifies as a personal attack, yes. It's essentially calling the other person shallow. And it's a really bad method of covering up yet another failure to communicate.
First he fails to notify itch of his remake plans, and responds to those telling him a note would have been nice with passive-aggressive posts like "I'm sorry you were surprised", "if you had joined my discord" and such, then he fails to manage expectations by mentioning that early scenes have been toned down, but overall content isnt reduced, and responds to the inevitably resulting misunderstanding with personal attacks.
This is not about soft skin either. I could care less about Jestur acting like a discord mod. He's the one that's ultimately suffering from his bad storefront manners. I just think that he really needs to improve his communication, and am not afraid to risk a bit of animosity to give him a pointer or two.
