The Fusion currently sells at a rate of about 16,000 cars per month. The Focus currently sells at about 12,000-15,000 cars per month, and even the Taurus sells over 3000 cars per month [Source:

It makes no sense to me why Ford would willingly give up potentially 33,000 sales PER MONTH. If those cars are not profitable, then I'd say there is a big problem with Ford itself. Versions of the Focus and Fusion are sold in Europe and presumably still will be, because they're quite popular there, so there wouldn't be much additional development cost to continue selling U.S. versions of them. You can't say it's a Union issue, because the Fusion is NOT made in a UAW plant but almost all the Ford SUVs ARE made in Union plants [information from the UAW itself, see
https://aflcio.org/UnionCars]. I guess they hope to sell enough highly-profitable SUVs to make up for it, but that's a really big gamble compared to a certain loss of 33,000 cars a month. There's got to be something bad going on with Ford for them to make a decision like this.
It also makes me a little sad to see an American company abandoning the car market and leaving it to the Japanese companies and Hyundai (Chrysler already abandoned it, leaving GM pretty much the only American company still playing in the field).
I have to say, though, that Ford kind of brought this on themselves. I personally stopped buying Fords after the last FOUR Fords I bought all had radios go bad about a month after the warranty expired: Ranger, Explorer, Probe GT, and Focus. And I really liked the Focus other than the radio issue, but fool me FOUR times, shame on me.
