Billionaire Elon Musk said Europe's largest airline Ryanair's CEO Michael O'Leary is "misinformed" after he refused to install Starlink internet on their planes, citing fuel costs due to drag. O'Leary reacted to this, saying, "I, frankly, wouldn't pay any attention to anything...Musk puts on that cesspit...called X...He's an idiot." O'Leary claimed the service would cost up to $250 million/year.
