When people started calling my personal mobile number with questions about a voluntary organisation I'm involved with, I was confused: we weren't sharing that number. It turns out that Google had decided to take the number I used to verify my identity for Google Business some years prior and start putting it in Google Search results. WTF, Google?
As far as I remember in Italy the situation was different.
You can ask to delist the number when you sign the contract and it was free. I am not really sure if in the case you decided later to delist the number you needed to pay a one time fee for that, but keeping delisted was always free.
Italy, and all of Europe, have always had a greater respect for personal and a lesser respect for business’ profits than the U.S.
