Also it is not really a spyware engine. It checks checksums. So you need to know the content to be of any use. People forget that if you are in the apple verge they know more than enough about you, they don't need a spyware engine. The thing is that they do their best to make sure that they do as little as possible of server side processing. Tasks like sorting photos, face recognition is all done locally as to ensure misusage and ending up with a big database of all sorts of data. They have chosen to do the same route with a very specific set of content checking. of course this tech can be used in malicious ways (banning books and what not) but if you live in a country that has a government like that, best is not to trust any device that comes with software preinstalled anyway
