Bombardier is controlled by the family though mulit-voting shares and they are not going to sell the cash cow business jet operations at current prices - to Boeing or anyone else.  Remember that this deal is only for the C-series.  The real loser here is the Quebec taxpayer.  A year ago they bought into C-series on a $2bn businesss valuation ($1bn for 50%).  Today Bombardier had to PAY Airbus (in future development costs and share warrants) to take control of C-series off their hands.

Well played.  Airbus.
