I didn’t downvote you, but perhaps it’s because you didn’t back up the word “criminal” with a source. What law does it break if facebook doesn’t send your post

I didn’t downvote you, but perhaps it’s because you didn’t back up the word “criminal” with a source. What law does it break if facebook doesn’t send your post to everyone in the group? If you wanted to send a letter to all of your friends in the traditional post, you’d have to pay 58 cents per person to do so, the business model hardly seems unusual.
