I'm a British guy living in Finland and am of course learning the language. I'm not sure if this article is a joke, but Finnish is quite a difficult language to learn quickly. However, it is true that Finnish has some great features, and I'm very lucky to be learning this than some other language.
I'm also a fan of auxiliary languages and think some of these constructed languages are a much better choice for a "world language" because of just how fast one can learn them. My personal favourite being Interlingue (aka Occidental). https://en.wikipedia.org/wiki/Interlingue
Related to both these points, there is a savant called Daniel Tammet, who is a polyglot amongst other things. I hear his favourite language is Finnish and he has constructed a language based on it (and other Finnic languages) called Mänti. I haven't checked it out yet, but it sounds appealing to me at least. https://en.wikipedia.org/wiki/Daniel_Tammet
