In previous decades, it made sense. Recipes sometimes used to be hard to find, especially recipes for anything unusual.
But, for anyone with internet access, there is now pretty much just one valid reason to really modify a recipe, and that's when the original turns out wrong and there's no better version of it to be found. (Leaving aside such inconsequential changes as preferring a little more salt etc.)
Why take "Recipe A" and clumsily re-jig it to make "Dish B", when you know that there's a 99.9 percent chance of finding ten or a hundred different recipes that will give you "Dish B" directly?
