This is clearly all posturing and intimidation. Do you really think M'OL would want to go into open court and either perjure himself or "air dirty linen"?
Just as restaurant critics have a right to be just that, critical, than anyone can air a reasonable opinion based on fact. Was the approach unstable, well it appears so. Does that make it unsafe, I'm guessing so. Just in the same way I can tell a Premiership footballer has had a bad game, having never been one, you can have an opinion on anything within reason.
