Ethan Van Sciver's war on Tim Lim has been going on since the summer of 2018. It started with Ethan going after Lim's Trump-themed parody books of that era as being unfit for comicsgate. Tim Lim won that battle because Ethan's audience wasn't quite ready to become a cult (yet).
Relations worsened considerably after Ethan and Tim Lim both attended Mitch breitweiser's great commicsgate summit later that summer. Mitch revealed his deal to get distribution in Walmart to the people that attended and offered to let them in on the deal. But part of the deal offered involved surrendering character rights and nobody took Mitch up on it. Ethan Van Sciver - Being Ethan - tape recorded the entire meeting and the theory has always been that he taped it for the publisher of Dynamite Comics. Dynamite comics was Ethan's undisclosed publisher for the first issue of cyberfrog.
The meeting was also the source of an eventual conspiracy theory where Tim Lim played Burglar Bill at Mitch's house and somehow stole nude photos of Mitch's wife which then (somehow) shared with everyone in comicsgate. By legend, there was some weird fap folder of internet comics women that was circulating among comicsgate at the time. The source of it was unlikely to have been Tim Lim, but it seems that someone let lewds of Mitch's wife go out among (by rumor) people like TUG. My theory has always been that the distributor of the photos was probably Mitch himself.
Then around Labor Day 2018, Ethan's negotiations with Vox Day broke down, Ethan unveiled his "warcampaign" and Ethan had to reluctantly become the "leader" of comicsgate to save it from the evil within it. Unless the dangerous people were kept out of comicsgate (by Ethan), everyone in comicsgate was going to be "cancelled" by the SJWs.
