All air traffic companies that bought Boeing 737 Max should ask for a refund and scrap those planes. Boeing lost for being so greedy.
It produced planes without caring about safety.

Boeing has been producing planes for ages. The accident ratio of their planes is not even up to 5%.
Boeing produced some of the best passenger planes in aviation history like the 737.
Your statement about Boeing producing planes without safety clearly exposes your ignorance about aviation safety and guidelines for aircraft manufacturers and the aviation industry as a whole. By the way air traffic companies (?) don't buy aircrafts, it's airlines that buy aircrafts. What has air traffic got to do with aircraft purchase?
