Speaking for myself here. Yes and no. Ranking by definition means not being neutral, it's just that society has decided that it's acceptable to rank spam lower than other content. Neutrality looks a lot like bias from the perspective of spammers. When you're dealing with more complex signals at scale there are so many second and third order effects that are hard or impossible to predict. For example, the conservative bias everyone's talking about doesn't seem to me to be literal bias against the right, but bias in favour of mainstream news sources which are overwhelmingly left-wing. I'm sure there are many issues in Search like the one I just described, and being able to have these conversations is what makes it possible for Googlers to spot these issues, decide if it's even an issue and fix it. If you ban a certain type of conversation, you'll change how people think about a potential issue.
