There are well-known historical analogues for many of the people now attempting to refrain from making political statements. Namely, there were those Germans in the Nazi era who were neither pro-Nazi nor openly anti-Nazi and who underwent so-called "internal emigration". And there were those Soviet dissidents who didn’t want to have any part in that decades-long fight between the West ("You Communist countries don't respect individual liberty and free markets!") and the Socialist Bloc ("You capitalist nations don’t respect workers, lynch black people and engage in colonialist oppression!").
Neither of those groups were "privileged", indeed these particular analogues were living in oppressive regimes that were suspicious of lack of enthusiasm and these people often suffered for that. But now, from our modern vantage point, we can have a lot of sympathy for them. They made a decision that was right for their own lives, and some of what these groups’ artists created may not have been fashionable at the time among all the polemic, but now it is seen to be very moving and have great staying power.
Of course, a big corporation with large government contracts is quite different from individuals choosing to refrain from being involved, or a small circle of people thereof that constructs its own shared private world to retreat into, separated from contemporary debates. But still, I think that we should refrain from condemning cases where one group of people has not joined its peers in adopting political statements or actions, even if we strongly sympathize with those political movements and believe them just.
