You just got me to go on Twitter for the first time in a long while to see if he had said anything on this whole fiasco. So here is what I found from him. Someone asked about it and he responded "no comment" and then when he got challenged on that:
I resigned in protest 3 years ago to push the company to ban Hate communities. I have nothing to say.
Feels like the API stuff or monetary loss wouldn’t be a the issue here, but he had an understandable disgust with some of the communities that were on Reddit and the inaction on them. Most likely wouldn‘t support fediverse (which also contains hate communities) and is still on Twitter unbothered by Musk and all that mess, which I think is fascinating considering how many more Q crazy MAGA racists I see now whenever I follow a Twitter link.
