I'm not sure that's right. In season 2, the one with the tv showing shows from different dimensions, Morty tells Summer that he's not really her brother, and points to the graves outside. Also, the first episode came out months before the rest of season 3, so I think that this one episode was made before the arrival of the female writers, although I'm not 100% about that.

The one that made me lose interest in the series was the pickle Rick episode, that had the female psychiatrist that's somehow smarter than him, so much so that the only response the smartest man in the universe had against her were the equivalent of fart jokes to attack her personally, that one of the female writers openly said was her self-insert.

Edit: Small correction to the above. The episode in which Morty tells Summer about his grave is called "Rixty Minutes", and it's the 8th episode of the 1st season.
