Extremely weak justification on their part, bordering on trolling. It's just marketing.

Easy access to malicious information hasn't proven to be the disaster these anti-prophets proclaim. For the last ~3 decades of widespread internet and search engines, you could trivially find all sorts of information (drug synthesis, explosives, etc.), and we're just fine.

(Corollary: easy access to good information did not make non-intellectual non-curious people smarter. Easy access to information does not have the consequences people immediately assume.)
