McDonald's is consistent, predictable, cheap, generic, and ubiquitous. Sometimes those are good qualities. "Good enough" is usually good enough, after all.
Regionally, there are a half-dozen choices that I'll take over McD's: Less iconic world-wide, but as cheap or cheaper, just as consistent, and more pleasing to the palate. I think that's closer to what they were advocating: Not necessarily building it in-house, but also not taking popularity as a reliable indicator of code quality (beyond a bar of minimum acceptability).
