I am disappointed but not at all surprised that a couple respondents develop on ATProto because of hazing and perceived unwelcome atmosphere on the fediverse in general.
Those kinds of people (the ones who gatekeep and haze) are why we can't have nice things.
Instead of an environment where I can build and feel comfort in the protocol's technical merit, I am instead frustrated by another protocol's success. Juvenile, I know.
I refuse to further platform those people.
