It's also due to, in the case of the Quebec government, nationalistic sentiment.
It's a difficult balance to strike - keeping and supporting high tech manufacturing, while trying to remain competitive. I think at the moment, the government intervention (blocking suitors and direct investment) is in fact doing more harm than good, but perhaps they know better - I have no knowledge of how competitive the C-Series really is or not.
The liberal party of Québec isn't very nationalistic, it's mostly that they have very deep ties to the Beaudoin family that has inherited Bombardier from their parents without having the competency to manage it. And our government is in the hand of corporations since we still have colonial institutions, so they spend our tax dollars on free loans that will never be paid back.
