I had such a different experience. I found the EULA surprisingly readible and easy to understand. Just 5 easy bullet points rather than a multi page document of legalese.
Their license simply says to include the license if you re-distribute the font.
Their EULA is, in fact almost exactly the SIL Open Font License, but someone decided minor changes in wording were more valuable than standardization.

It DOES use SIL Open Font License. Maybe it's dual licensed?
