Eastman and Laird were taking potshots at everyone because they had nothing to lose, and were both having fun and working hard. It’s a specific kind of indie spirit that I’m glad to see all over the place in webtoons and webcomics these days.

From what I’ve heard, ‘TMNT’ is basically a wide-reaching parody of the comic genre at the time. ‘Daredevil’ was one of the influences, just like noted in the Wikipedia article:

The concept parodied several elements popular in superhero comics of the time — the teenagers of New Teen Titans, the mutants of Uncanny X-Men and the ninja skills of Daredevil — combined with the comic tradition of funny animals such as Howard the Duck.

They developed a backstory referencing further elements of Daredevil: like Daredevil, the Turtles are altered by radioactive material, and their sensei, Splinter, is a play on Daredevil’s sensei, Stick.

Idk how you read that article to have missed that. It’s also been noted more than once before that the ‘radioactive spill’ or whatever by which the turtles are affected is supposedly the exact same incident that is Daredevil’s origin story.
