When he says 'my own articles' he means articles he authored for the community he is founding, that all rewards on go to that community. Look down two paragraphs and you'll see where he states that. He isn't self voting and getting the author rewards. He is authoring posts for a community that is getting all the rewards for the post, and all he has to support the fledgling community is his stake.

He says he doesn't care, but in his last post he talks about how fearful he is of getting DV'd. He repeats it over and over, and talks about how many posts he has not published, and his constant worry over how to censor himself so that he won't get DV'd.

The people we meet all have trauma they deal with in different ways, and when we discover the particular triggers people that haven't dealt with that trauma successfully, we can quickly drive them to act in unreasonable ways.

His fear about being DV'd has caused him to speak irrationally, because he isn't self voting and rewarding himself, but rewarding the community he is trying to support with his stake by upvoting the communities' posts. He just happens to be the author of those posts RN, because he's creating the community.
