It isn't about what they are willing to pay for, it is about how much they are willing to pay for it. A "realistic-sounding, 80% correct version of an expert opinion" only costs US$20/month–and if you are willing to compromise a bit on correctness and/or privacy, you can even get it for free. No way you are getting a real expert at that price. Whereas, pool $20/month across millions of subscribers, and suddenly you have enough money – and, more importantly, future revenue growth prospects with which to convince investors to give you even more money – to afford roomfuls of real experts to try to get that "80% correct" percentage higher.
