I mean I think you answered your own question why no one has shared this article, a vast majority sounds pretty asinine.

• Will there be big companies jumping into the fray when shit gets frothy? Yes, money will follow money.
• Will people openly adopt across the entire marketplace, what those big companies regurgitate out tech wise that probably already exists in the marketplace? Some will. Mostly only new people into the space. Those that have alternates will already be set up and probably won't migrate off something that is already working. Dont fix what ain't broke.
• Will all of them? pffft. HA.
• Will a majority of them? Meh, not likely in the short term, and not amongst the community who hates literally anything decentralized. Only newbs would trend towards those things because trust hasn't been developed.
• Banks are trusted? Someone hasn't read a history book, or know anything about why cryptocurrency exists at all, so there goes all the credibility of the author.
• Facebook Apple Amazon Netflix Google offering anything on the tech front will be just a better funded Ripple. These big companies are going to try to take the tech but will not remotely accept ANYTHING decentralized, because they want to control everything. A vast majority of the people already in the community will continue to hold their sentiments against centralization.

So ... I seriously doubt everything that article takes as givens, pretty much 100%.
