Sounds a bit like they are a startup with very limited time and resources to me. I hope they haven't outright lied about endorsements, however they are building something I quite like the look of and would find personally useful (especially after the horrors of my terrible YC application video), however it looks very expensive to run... I think free is a bit of a worry but it also implies they might not have built that bit yet. Let's see if they show up in the comments to assuage your concerns.
