To my knowledge neither of these conditions have occurred in response to the 737 Max technical issues. Corporations listen to customer complaints that are backed up by losing revenue - as was shown with the issue where a passenger was beaten up on a United flight, people are extremely price sensitive when it comes to flying - there is math that can make the 737 unprofitable, but I think it's unlikely that the math will turn in that direction, it would take an extremely negative PR issue to start this.
