The license the author of the BrainFuck example has chosen (or made up) actually is pretty restrictive, if not immature. Software licensing is not a joke. The author's account on Github seems to have many projects were a license has been either made up, or adapted. Perhaps out of lack of understanding current licensing and available licenses.

I'll go ahead and feed the troll: please back up your statement that the license won't hold up in court. The site you link to has an entry for the "do what the fuck you want license v2" and there is literally no warning, and the only restriction mentioned is that a change to the license text requires a change to the license name. So again: exactly what is the problem (beyond hand-wavy unevidenced claims about judges)…
I agree with Alupis that WTF is an unfortunate license choice for many projects, since it introduces a lot of legal uncertainty. But I also agree with most commenters in this thread that for this particular project, it doesn't matter. Cool though it is, no one is going to use this code in a commercial project, or as the basis for another OS project.
So it really doesn't matter in this case.
On the other hand, if someone writes a TCP stack in ARM assembly and licenses it under WTF with the intention of letting other people use it in their projects, there's a potential problem. It's not just corporations who will avoid a non-standard license, it's many established open source projects as well (for the same reason: legal uncertainty).
