Bullshit.
Examples are the best excuse to not write documentation.
I should be able to come up with an example by looking at the docs, not the other way around.
I just LOVE IT when i read a device datasheet, perform the steps and things don't work. Then i have to download a couple of GB or so of framework and configurator to generate a project that shows me all the details they forgot to put in the datasheet: order of operations, missing requirements, all that stuff.
Even better when the examples are not updated when the device / libraries / framework are updated
