I don't disagree with that, but the market for lemons still doesn't really fit.

If I remember my econ class correctly it uses used cars as an example. If you're neighbor bought a used Toyota and tells you about it being a great purchase, you can't go out and buy another used Toyota and expect it to also be in great condition. Every car is a gamble.

But if you use something like Hubspot and tell your neighbor it's really good/bad you can expect to receive the same Hubspot service they did.
