I have no idea about this whole situation, honestly, but as someone coming into this with very minimal knowledge this document is very vague and confusing. I understand he probably wanted to avoid mentioning any specific names, showing identifying images or perpetuating leaks, but he probably could have explained the context around the situation and what the censored images were supposed to show.

The arguments used to strengthen his claim are themselves also not very good. The "Why would I leak?" sort of argument doesn't really work, because it expects you to imagine that Aruvn has the sort of character that wouldn't leak, but fails to actually establish that. "How would I benefit from this?" also doesn't work very well, because there are all sorts of purposes one could imagine.

I also don't think there really was a reason for him to include the fact that he doesn't like news tubers or that he trusts in Nijisanji. People who agree with those opinions may think otherwise, but I don't think they were necessary, diluting his message in the process.

Overall, it's a very badly put together document for something that came out a year later, and still very emotionally charged. I wonder why he decided to post it now.

Actually, he was mentioned here earlier today and speculation was brought up, so I guess he might have seen that after looking up the discussion on his recent concert. That (or any other discussion of the rumour in conjunction with the discussion spurred by the concert) is a likely possibility for what prompted it.

I don't mean any ill will toward him and I probably believe what he's saying, but he certainly chose a weird way to put it.
