His comics weren’t offensive because they criticized a practice that is done by (a very small number) of Jews, they were offensive because they conveyed the message that all Jews did it.
You may make a comic calling it wrong without equating it with judaism, but in reality I think the Jewish community already has it figured out and can probably talk about the issue with more nuance than you can, and so it is probably best to leave it to the professionnals.
Before esim, a lot of sim swap attacks were done by bribing a rank-and-file support guy from the carrier to issue you a new sim. Nothing new here.
