A Catholic priest's private location data from his smartphone was obtained by a Catholic newsletter and used to out aspects of his private life. This occurred because personal data, including from apps like Grindr, is collected by apps and data brokers and sold with little regulation of how it is used. Experts have long warned that insufficient protections allow supposedly anonymous personal data to be de-anonymized and used against individuals. There are some steps people can take to protect their data privacy, but it requires vigilance that most people cannot reasonably maintain. Stronger regulation may be needed to better safeguard individual privacy as personal data is increasingly commodified.
