It's laziness and for most of the public and unwilling desire based on perceived lack of need to properly understand the metric system. In this case most Americans "know" that a meter is "a bit more than a yard" and since most won't care that much about the size of this thing, when someone says "three square meters", most will round it off to "about 9 square feet". Granted in this case the article should have said for the lazy "somewhat more than 9 square feet" or something like that. Sorry, the metric system never caught on over here except for large soda and water bottles, drugs, wine and distilled spirits.
