Ya I was just a little confused by the title "1,200 slide decks by category...". Its perfectly fair to promote your product while providing a free service, but it does raise a mental flag of "if the goal is to promote product A, how valuable is token service B?". Regardless it's good to know these slides exist and reviewing them will help a lot of people (though I pray people skip the Theranos one as something that will influence their own companies).
