If a problem is systemic, "whataboutism" is an appropriate critique (in lieu of being able to articulate the underlying issue) as it typically makes reference to something that is a populist concept, to be effective as a recognizable objection.
In this case, the objection is apt and needs to be addressed with more than hand-waving because it's troubling.
Saying "google is different because it helps shape culture" as opposed to Amazon's Chinese presence. Amazon's service is an opaque service-oriented mechanism...is an appropriate response.
