This is a fine mentality when it takes a certain amount of "Internet street smarts" (a term used in the article) to access the internet - at least beyond AOL etc.

But over half of the world has internet access, mostly via Chrome (largely via Android inclusion). At least some frontline protection (that can be turned off) is warranted when you need to cater to at least the millions of people who just started accessing the internet today, and the billions who don't/can't/won't put the effort in to learn those "Internet street smarts".
