I would not have guessed "getting domain verified" required less activation energy compared to "making posts" for some organizations
Perhaps it’s more that they feel posting does not provide value, but establishing an official account as a way of preventing others from claiming to be the official account does provide value.
I could imagine “mitigate brand risk” being a higher priority than “generate incremental brand value”
posting with your domain name is serious business
Parking a handle vs permission to communicate to the public? I can understand that.
