Is it ideological speech though? The issue is more subtle than that. What Google is doing seems much closer to a public service IMO. The question in my mind is, based on Google's positioning in the market how much does "common carrier" and "net neutrality" apply? They seem to be in a bit of a grey area. If they are an opinion site, yeah, 1st Amendment, no doubt. If they want to come out and communicate something completely separate from the search engine like a manifesto, that's also 1st Amendment. But the messaging and expectation from users is that the search engine is a machine without bias. Presenting something as unbiased when it is biased could be considered fraud. Also, is Google a curator of information or a generic provider that merely connects multiple parties like the postal system, ISPs, etc? If so, should net neutrality apply? One approach they could take is that the algorithms just reflect the information that is available and merely mirrors any bias in society. Then again, that raises the question of whether AI is racist, sexist, left/right wing, etc; and whether something should be done about it.
