Well, that's the marketing interpretation of "blockchain", the same way the media use "hacker" nowadays to indicate anyone who breaches an information system. A blockchain is simply a data structure. In git you can achieve 1 by signing commits, 2 by simply comparing what you have with everyone else has (if the majority of the network wants the history to be changed it will change, no matter the technology), 3 can definitely be achieved even for cryptocurrencies (51% attack and the like). At the end of the day distributed trust literally means we all trust each other to do the right thing because, at the end, it's more cost effective and more beneficial for everyone. Directly from the Bitcoin whitepaper: "The incentive may help encourage nodes to stay honest. If a greedy attacker is able to assemble more CPU power than all the honest nodes, he would have to choose between using it to defraud people by stealing back his payments, or using it to generate new coins. He ought to find it more profitable to play by the rules, such rules that favour him with more new coins than everyone else combined, than to undermine the system and the validity of his own wealth."
