It's a hard balance. Free-traders tend to be find with other governments effectively giving some of their money to the country where the subsidized product is exported to, but as a peer comment noted, this can result in consolodation of the manufacturing of that equipment in the country that is subsidizing. So then in the long run they can raise prizes because they have the monopoly on producing that product. We see similar behavior with Uber and Lyft today (trying to subsidize the riders to get people on their platform). But this is a government doing it, which tends to have much deeper pockets.
