Ford had a sedan winner on its hands when it released the first gen Fusion in 2007, then the winning continued with the modest refresh of 2010 and with the move from the Mazda to Mondeo platform in 2012. Ford did NOT lose "billions" on these products. Certain lower trim levels were categorized as "loss and low" meaning loss or low profit per unit -- but the entire vehicle line did not lose money. Ford did shoot itself in the foot with the 2012 Fusion however, when quality was a major issue at launch and beyond and it was a shame because Camrys and Accords were seen as trades on Ford Dealers lots for Fusions for the first time in a long time. Then to make matters worse, Ford did not reinvest anything significant in a refresh of the 2012 design which further eroded market share. Then the dunces announced the Fusion was "dead" in Q1 2018 -- over 3 years prior to the actual run off of the product. Talk about stupid.
Ford just does not get the long game. There will always be a market for sedans, they won't be the primary driver of profit, but they will provide entry level buyers among other things, not to mention trade ins so desperately needed especially today by Ford Dealers.
