the Austrian Data Protection Authority (DSB) has decided that the use of Facebook’s tracking pixel directly violates the GDPR

The DSBs decision to declare Google Analytics illegal, also applies to the “Facebook Login” and “Meta Pixel” tools provided by Meta: If these tools are used, data is inevitably transferred to the USA, where the data is at risk of intelligence surveillance. European website operators are therefore advised not to include any tools from Meta on their websites.
