From the article:

Less than 500 were built, due largely to Allied bombing raids that destroyed most of Henschel’s production facilities.

I've heard right here that bombing factories was a waste of time and inhuman.

Yes and no. We might have accomplished the same thing by bombing hell out the rail marshaling yards.
Which is exactly what we did prior to D-Day. It eventually got to the point that the Germans had to road march by night to get anywhere.

The above ground factories were for show. The Nazi's moved their production underground way before 1944. Sometimes though production remained above ground in "bombed" out factories that actually were functioning perfectly but looked kaput from the air.
