Specifically, do they make a big stink over this artwork, in the context of WotC having also done Quests from the Infinite Staircase and Tales from the Yawning Portal, which are chock full of classic goodness.
Classic goodness... that includes an adventure in a spaceship.
So, are you complaining about high heels in a fantasy game that also has... robots and laser guns? If not, you're good. Don't feel a need to defend yourself if you aren't doing that.
If you are doing that... well, that's a choice you get to think about, I guess.
This post, and
@Levistus's_Leviathan's, make a similar error...they assume that if someone is complaining about the new artwork they are ok with everything else (Ravenloft, Eberron, Ravnica) that has been published and therefore their position is incoherent. Basically, characterizing the complaints as if they are about this one specific thing and therefore silly and wrong rather than part of a more cohesive viewpoint.
For example, many people that dislike the new direction would also not be fans of other departures from the medieval. And I've talked about this point a few times, but imo the issue underlying the complaint is how easy it is to find games that fit your preference. If you meet some strangers and say "let's play d&d", what is everyone imagining? Is it at all similar?
The converse of a wider variety of games being possible is that the brand identity is less clearly defined. This is unavoidable.
You can respond to this tradeoff in many different ways--and obviously by keeping the brand identity narrow, you
are going to make some people who may want to play d&d feel less interested. But I think it is important to note it is a real tradeoff, and people who feel frustrated as a result are not just upset because they are unreasonable people.
(Edit to add, to be more charitable to
@Umbran. The fantasy spaceship goodness has coherence with respect to genre from the pulps. I think it is possible to like that kind of genre in d&d without wanting other genres...the ask here is probably as much about genre as historical accuracy).
