The backlash exists because most of his writings consist of regurgitated ideas plucked from elsewhere that he attempts to pass off as his own as though he's some sort revolutionary thinker in the modern era. Then he sells tickets to his Friedman Forum for $1K a pop to people who aren't read-well enough to realize as much.
So your issue with Friedman is that he's aggregating, popularizing, and improving the accessibility of new ideas that he himself didn't create?
Sounds like any number of journalists/writers to me.
Do you really feel that he has an attribution issue? He seems to always put the focus on people at the forefront of the change he describes (for example, in this article the focus is on Chesky.) It's not like his articles are some TED like exercise, where he portrays himself as being at the center of making all of these new things happen.
