No moderators/admins were involved in the closing of that question, only regular users. You said in the comments there that you meant those users as a collective.
In that case they are referred to as high rep users.
No site can have this question because the "Not Constructive" rule is a network-wide rule: it's valid anywhere by default. As it's been underlined before, that question cannot be reasonably and definitely answered by someone who isn't a Microsoft representative member, that's why the question "might solicit discussion, arguments, etc". External developers might not be able to answer it if the reasons are "company decisions" so we're still in the realm of the unknown.
I'm not an active member on SO so my advice is (as for any other closed question): if the question can be edited in some way (that I'm not aware of), then that would be the only step for its reopening. If it cannot be edited, I'm afraid it will stay closed.
Alternatively, if you can find documentation about such decisions then I suppose that that could make the question constructive again (in case the question stays reasonably scoped, of course). By the way, these "on the edge" questions can be asked anytime on chat. I'd ask there in case the question stays closed.
