It's business, not personal.
Whenever there are supply chain disruptions, politics come into play. By politics I mean relative strengths of the companies. All else equal, larger companies with larger orders will always get priority over smaller companies with smaller orders.
Plus look at the downstream impact for each company. When you have someone like Al Baker at Qatar ready to trash talk to the media at every opportunity, you will get attention.
Consider that P&W will cut total engine deliveries by 25% this year, but deliveries to Bombardier will be cut by over 50%.
That means Bombardier is taking a disproportionately large impact of the shortfall, or to put it another way, P&W is prioritizing deliveries to Airbus rather than to Bombardier.
