Holy gossip?

I was thinking about today's Gospel reading. Jesus healed a deaf man and as usual told everyone not to tell. And as usual they went and told everyone they knew.
I wonder sometimes why Jesus told them not to tell others. As God, He had to have known they would tell the whole world (after His death and Resurrection quite literally). So why bother?
My personal theory is that He realized gossip travels faster than any other kind of news. So by telling everyone to keep it under wraps, He might have been encouraging them to speak of Him far and wide...
or perhaps I am just cynical.
