Europe’s General Data Protection Regulation (GDPR), a law changing the requirements for data collection disclosure, went into effect on the 25th of May. To date, the Tronc and Lee Enterprises publishing conglomerate has not complied with the regulations and have had their outlets blocked in Europe. Blocked sites include the LA Times, Chicago Tribute, the Orlando Sentinel, and the Baltimore Sun, among dozens of others. The GDPR requires that companies demonstrate a lawful basis for their collection, a requirement that applies to all companies based in or providing services to people in the EU. The most visible impact of this regulation for consumers in the EU is their requirement to consent to data collection on every website visited.
