According to the description of this last case, it seems like case 166 is about sharing personal data with third parties which aren’t involved in the services’ operation, whereas case 188 would mean the service may share personal data with third parties working with them.
If I didn’t misunderstand the meaning of these cases, I think we should rephrase their titles or change their descriptions to better reflect that.
Case 166: This service shares your personal data with third parties that are not involved in its operation | (with a higher weight)
Case 188: This service can share your personal data with third parties involved in its operation | (with a lower weight, and move it to the Third Parties topic)
