Generally speaking, the current generation of large infra/content providers do not appreciate countries taking advantage of their services to harm their customers and will intervene to negate or deter such actions.

I'd describe that as being aggressively neutral, not picking sides.

Why not?

They used to explicitly have a "do no evil" slogan. It'd be good if it survives somewhere in their culture for times like these.

I fully expect them to be on the side of the US, always. Why would you think otherwise?
