Honestly I think this is a ridiculous take. Google's military contracts have been extremely controversial both publicly and inside Google. The thing is, if Google wants to exist in China, they must follow some orders. The US government agencies do not force that kind of control (that we know of) so they are more easily rejected. Project Butterfly and Project Maven are not even directly comparable projects also, they have very different goals and implications.
All that said I do believe Google and others need to face some sort of regulations and audits. But hunting for Chinese intelligence officers seems like a waste of time with little evidence to actually warrant such an investigation.
Apologies if this is written weirdly, I desperately need sleep.
