My problem nowadays is with the idea that Google, et al, all believe they're own myth of being the best at XYZ user experience and if you disagree then you're a curmudgeon or an idiot who "doesn't get it".
Why wouldn't they put a button like that? At what point did optionality and customization of your user experience become undesirable to the point that you need to obfuscate or prevent it?
My guess is that too many people read Don't Make Me Think as dogma and now we're in a world where the tech industry assumes they need to do all the thinking for anyone that touches their product and the users brought up in this world have no idea what it's like to not have their UX dictated to them.
They already have a button that would cause far more confusion if accidentally pressed (Feeling Lucky) since it results in a page that isn't a set of google search results.
Sorry, gotta say that those are pretty weak counterpoints... I expected something about how Google's business interest has everything to do with personalized search and each non-personalized search would result in less revenue, or something like that.
