I understand it's their "right" to censor whatever they want (well, the EU may disagree with that, though, given Google's dominant position in search, and the FTC should, too, but this is America, the land of "corporations are protected from punishment"), but it's also people's right to call them out on it. Just like it's people's right to call out Google [1], Facebook[2], and Twitter[3] for censoring links and hashtags for political reasons.
