I almost entirely agree, and I think the word "favor" wasn't the best choice. My opinion is that many developers will often consult Google or Stack Overflow before consulting a manpage or documentation or will only briefly consult documentation before a Google search. I'm definitely guilty of this, especially when I'm under a tight deadline, but I think it's a behavior that should be avoided when possible. Navigating documentation and/or manpages forces you to engage with the structure of the tool you're using, Google and Stack Overflow do not.
