Microsoft and Google have both announced that they will be blocking thousands of search terms in Bing, Yahoo and Google. They claim that it is to block the spread of child porn, certainly a noble cause, but is that really their motivation?
Search-term blocking is very crude. Not only will it block legitimate research and porn searches equally, it is also a broad net that will capture and block information completely unrelated to child porn. Worse, everyone knows that this censorship will have absolutely no effect on the distribution of child porn.
These companies know that child porn is distributed almost exclusively on the Dark Net. Child porn consumers don't search openly on Google or any popular search engine, nor do purveyors distribute their wares openly on these platforms. So why are these two US companies acclimating the populace to censorship?
