Good for our government, standing up for our national and commercial interests against a cheap bullying tactic by a hypocritical competitor with all levels of U.S. government in its pocket. 

Online aerospace magazine AINonline reported in March 2015: "Boeing since 2000 has received $64 billion in federal loans and loan guarantees—all from the Export-Import Bank—another $457 million in federal grants and tax credits and $13 billion in state and local subsidies. It leads Ford, General Electric, General Motors and JP Morgan Chase as the top five corporations in receiving subsidies from all levels of government." 

"Boeing also stood out as a 'double-dipper' among federal contractors by landing $18 billion in contract awards in Fiscal Year 2014."

By contrast, the Canadian government has given Bombardier an interest-free loan that must be repaid, and the Quebec government has invested in the company--presumably in expectation of a return on its investment.
