I think, you underestimate for how many people this works. Non-technical people very much orient themselves based on what they know they can trust. If they don't understand the consequences of something, they will try to err on the safe side. See for example anti-virus software. This will is not terribly strong, as even already having to remember a few more letters in a password can completely shatter it, but in the case of Firefox vs. Chrome, that difference is practically nonexistent for the average user, so being told to use Firefox, because it's safer for you, for reasons that you don't understand, but smart people say it, so it's probably true, that can very much influence them to switch over.
