First, I'll start by saying that, all things considered, you're not doing a horrible job, despite the reaction you're getting. So don't let people or things like this copypasta get to you too much. I think most people, at some level at least, know that a lot of their gripes aren't your fault and that you are just the messenger getting shot at and that your job is really tough, at least in situations like this.
Anyway, I think you are looking at it this specific thing the wrong way. It wasn't that you asked a question or asked for feedback. It was how you asked it.
You posed it as "isn't it kind of your fault? Now prove how it isn't" or something like that. No matter what, that's going to rub people, especially already frustrated people, the wrong way. Call it, not knowing your audience, or not reading the room, or whatever.
You're kind of missing the fact that people don't generally like to git hit with a devil's advocate argument in general. It's usually pretty annoying. Then add on top of that the fact that this one was kind of blaming the players for a part of the game that they don't like and have been begging to get attention. And then add on top of that the overall response from Supercell/you about the dissatisfaction in the update.
A much more effective way to ask would have been to actually ask bluntly, with no hypotheticals or devil's advocates or anything like that, how people think it can be fixed or ideas they might have to make it better and so on.
