It is possible that neither are more manipuled tough it's impossible to tell. What seems clear from your example above is that both are manipulated, just in different ways and with google's incentive. It is understandable that countries came to the conclusion that this is posing a threat to their national security.

"Manipulated" has strong negative connotations, but it could just mean that the results are chosen and controlled by the search engine. In which case, it's a meaningless statement. The entire purpose of any search engine is to choose results for queries.

Or it can mean the results were altered from some ideal baseline algorithm that we consider unmanipulated. The only obvious candidate for this baseline would be the search engine's regular algorithm. But if you're saying that's not the baseline, then it's unclear what you consider to be the true baseline and therefore unclear what "manipulated" means.

I agree that countries may consider search engines, social media, or anything else that can affect flow of information to be a national security threat.

And what, exactly, is the national security threat here? If Google is manipulating results to favor its advertisers or the political positions of its owners, that's what all publishers do, and have always done and nobody ever called it a national security threat. The "national security threat" here seems to be that they are showing people content that the government doesn't want them to see.
