He may use Signal, but he does not want people on X to advertise their presence on any competing platforms. It is a childish and protectionist policy, and in no way align with his Free Speech® claims.
It was the same when URLs to Mastodon/Fediverse instances was banned on X, in an attempt to hamper the network effect for those who migrated. Meta does the same with Pixelfed these days, to hamper migration away from Instagram.
