You can leave a comment (which I just did – I went to Meta to search for the poll, and found your question already waiting).
The community has decided that questions about chess programming are on-topic. This is also stated in the help center: Chess-specific questions about programming a chess engine or other chess software are welcome.

Hopefully, that will remind the close voter that the Community has decided that this is in scope, it's not a one-sided decision by the ♦ moderators or Stack Overflow the company.
We'll probably get programming questions which would be considered too broad on Stack Overflow; I think that's fine, our standards don't need to be so high; because of the low volume we can handle bad questions with ease. However, I do think it's important to stress the authors to provide a Minimal, Complete, and Verifiable Example. Chess Stack Exchange should not become a debugging service for chess engines.
In those cases, using the standard 'not in scope' reason isn't really constructive. The author of the question will visit the help page, but will see nothing that explicitly says their question is off-topic. I'd recommend using a custom off-topic reason then.
