Davisson is a bit of an infamous translator with a massive ego who likes to top bill himself over the mangaka whose work he translates. Like if he translated the Dragonball manga he'd put "Dragonball, by Zack Davisson and Akira Toriyama" and thinks he's the reason people read these manga rather than the original author's story. He's also friends with ANN, and you can see some ANN people liking and commenting on the tweet, plus Erica Friedman, another translator who gushes about gay shit. And Shane's there too. Dominique Skye also. I guess everyones going all in on this chart being proof of something.
But hey, remember, just because a guy in the industry makes this tweet about con owners should be 'warned' immediately after the Ireland con announced Vic doesn't mean there's some kind of motive here or silly conspiracy or anything.
