Only a decade?
I think it was 2001 or 2002 when I looked at Handango and Jamster - both of whom took 30%, and more to the point took complete control of distribution - i.e. all they had to do was put your app below the fold of their web page, and you'd never sell anything - and I remember thinking at the time, "Seriously, what idiot developer is ever going to buy into this?"
The internet gave me my answer.
