Incomplete quote: '...dimensionless ratios between free parameters or physical constants appearing in a physical theory should take values "of order 1" and that free parameters are not fine-tuned.' It just means that theorists are suspicious of theories where the parameters have to be adjusted to high precision to match reality. That's reasonable grounds for suspicion, but it's not natural law.
