> None of this is publicly available. I received message on WhatsApp from someone claiming to be my LinkedIn contact, I asked how that person got my mobile number and was told my number is visible on my profile. I didn't remember ever adding my number there, So I dug around to find that LinkedIn published my phone number to all my contacts when I uploaded it for 2FA (LinkedIn didn't have TOTP that time. You needed to have premium account to prevent it from being shown to contacts. I removed the 2FA until LinkedIn got TOTP. LinkedIn IMO[1] has received far less scrutiny on its practices and content when compared with other social networks while having disproportionately large influence on professional life.
