What community reopened it? It did not get reopened until after I posted here, and people came from here to reopen it. The discussion on meta, and comments here from people who are clearly actively involved in site moderation on stack overflow, shows overwhelming agreement that it does not belong there.

I would be willing to bet money that your opinion that it is on topic would come as a surprise to them. I would also be willing to bet money that if the question and answers came back to the attention of the majority of people on meta, it would immediately be closed and deleted again.

If you think that this is a problem, perhaps you should say something publicly. Because it doesn't seem to be an isolated or even particularly unusual occurrence, and it is costing you contributers.
