Not necessarily:

No Score = higher risk, higher interest.

Incorrect low score = perceived higher risk, higher interest rate.

Depending on how the risks of no/low score are weighted, and how wrong the inaccurate score is, a person may very well be more harmed by no score than by a low score. An inaccurate score might have to be massively off the mark to make a person worse off than no score at all. In the US for example, people with no credit history often get interest rates as high or higher than people with a relatively low credit score.

Of course from a privacy & data protection standpoint this doesn't make silently and secretly profiling customers okay. The solution is probably something more like a transparent opt-in system that has easy access for the customer to review their data and decide which pieces of it are included.

In the US, the balance is skewed a bit more towards secrecy, and it's not opt-in either. However you can with only modest difficulty check your credit score & information used to calculate it, and challenge parts of it that you think are inaccurate.
