I think the bigger problem is that these adjustment appear to be done manually. We know that's what they're doing to avoid racist autocomplete phrases (and reasonably so, I think most people would agree). Having such judgments made on specific political topics/events/scandals will inevitably result in political bias, especially in an organization whose workforce is so politically skewed to one side.
This is the problem with search query anecdotes, it ultimately produces a subjective and pointless debate about how one should interpret search suggestions for arbitrarily selected one-off queries. There is no methodology here, and we don't even know how widespread any particular suggestion results are. Any person with an agenda will be able to cherry-pick search queries that confirm their narrative.
Also, if I type "hillary e" I get "Hillary Emails PDF" as an autocomplete suggestion. If I type "clinton e" I get several email suggestions "clinton email PDF" ,"clinton email film", "clinton email FOIA", "clinton email download".
Please include these confounding results in your analysis
