Certainly, but if the examiners would be accused of asking a too difficult question, as the article alleged, this would be defended by showing a more elementary approach. Or both of them, wouldn't hurt to have more ways…
Let's put this in the context: the article is about problems which are supposedly killer problems because they require some hard-to-get hint to solve. Therefore, a hint is low quality, if another hint exists that is…
Unfortunately, these "ideas" for the problems are low quality. Problem 2: "use derivatives". How the heck that helps if F does not have to be continuous, let alone differentiable.
