He might trick them into thinking he was behind Anita's success.
He was, though. Anita isn't quite the true believer Joshathan is. She needed someone who has steeped themselves in modern feminist, patriarchy, and privilege theory to write for her. Joshathan has been living those theories for his entire life. He knew what to write to make it sound 'academic' and to hit all the buzz words. There's a reason she needs to read from a script at every speaking event or public(ish) appearance; and that's because she needed Joshathan to write for her.
But, because he's such a wimpy cuck, he made sure that everything Feminist Frequency is and was was under Anita's name, and not his. He wanted to be behind the scenes, and make it look like Anita was not only the face, but also the brains behind FF. And that's what fucked him over. He and Anita made such a big deal about her not being his puppet, that when she dropped him, he has no ability to really tell anyone how it really was. Because they made sure everything was in Anita's name, and because if he tries to say anything that shows he was the mastermind, he not only proves right everything said about the pair by detractors; but he also becomes just another butthurt privileged white male trying to take credit for a woman's hard work in the eyes of the true believers.
In the end, it's lose/lose for him. He will never give grobbitygibbiters (It gets hard to come up with nonsense words to sound like these SJW idiots, you know; probably because I don't have the mentality of a 5 year old) the pleasure of letting them know they were right about him and Anita. He also- because of his lifelong indoctrination- can not make it appear that he really is an asshurt privileged, supposedly straight, white, supposedly cis male; or he becomes literal Satan not only to those in SocJus, but also to himself.
He's so deep into self loathing because of how he was born, and he's made sure to project that self loathing as real concern for women/people of color (what are we, back in the 50's with this term?)/LGBTQIWhateverthefuckotherlettersaregettingaddedandremoved/communists.
It's so glorious.
