As for the claim that Alexa is hard to monetize, not really. It's always baffled me how teams can jump head first into pitfalls of monetary loss in that sector, and just keep swimming. Amazon fought to have the competitive edge, and once they had it... nothing.
I'll have to admit, I'm actually curious to see what's next. Change is good.
