This simply opens up a place in the market for uncensored book sales. If I want an honest search of the web I don't go to Google because they heavily censor and bias their search results. If I want to peruse the true set of literature on a particular topic I don't go to Amazon for the same reasons. I really don't see this "safe space" strategy paying off for these major tech brands. The holier-than-thou internet simply makes itself irrelevant. People can tell the difference between an honest retrieval of information versus a heavily censored retrieval of information in accordance with some ideological canon.
