I think what's not ok and not run-of-the mill (or bloody shouldn't be) is quite such blatant corporate cronyism at the very top of the United States of Umurica's administration. Yes lobbies etc always influence policy but actually having ex board members of a given industry handling the legislative portfolio as the same industry is always going to be wide open to corruption if not favouritism.

What divides the acceptability of state support for particular companies is your definition of national interest. If that national interest is the individual's "free" choice, then industrial favouritism is clearly wrong. If however you understand national interest to be the GDP bottom line (and by extension that of state champion's of industry), then it's a-ok.

T'is funny for France to complain about states' meddling in industries and leveraging state resources to the benefit of state champions... But then it's also equally absurd to hear the US protest against EU support to Airbus. The biggest joke is that Airbus and Boeing then point to each other saying they did it, so we need to aswell to keep things fair!
