I agree with your sentiment. There's no denying that they are a valuable tool for language learners, but they do not have the monetization figured out yet. Originally they were going to provide translation services, which hasn't worked out. Now they're trying to provide certifications for people who pay a fee. Will that work? Maybe it will. What feels odd is that the valuation is so high for a company that hasn't yet figured out a reliable way to make money from what it does. If all else fails, they could install paywalls, but a substantial portion of their users might abandon them at that point.
