No, I am not interested in joining your proprietary social network

I don’t care whether it’s ello or sgrouples or FriendFace or app.net or whatever, I am not joining another walled-in social network owned by a single organization. I already have enough of those. I don’t care if it has a strong privacy policy, I don’t care if it has good security, I don’t care if it has no advertising, I don’t care if it will let you remain pseudonymous, I don’t care if the people who own it are really cool.
