I though that the point of the article was that Amazon's hardware strategy isn't working, completely ignoring the echo. The title then invites us to draw our own conclusions about the echo, and enjoy the irony...
Amazon Has No Taste is a pretty good title if you ask me, it's an excellent summary of the problem.
Amazon's Echo Chamber doesn't strike me as that bad, it also seems to describe the problem decently. Amazon is big enough and has enough eyeballs that they can make mediocre products appear to succeed for quite a while. Because of that insulation the products don't improve nearly as fast as they probably should.
So I call it clickbait.
Maybe call it Amazon's Echo Chamber instead.
