Facebook owner Meta and other online platforms must not force users to pay for the right to data protection enshrined in EU law when offering ad-free subscriptions, the European data regulator said Wednesday.

"Online platforms should give users a real choice when employing 'consent or pay' models," the European Data Protection Board (EDPB) chair Anu Talus said in a statement.

"The models we have today usually require individuals to either give away all their data or to pay," he said. "As a result, most users consent to the processing in order to use a service, and they do not understand the full implications of their choices."

Meta in November launched a "pay or consent" system allowing users to withhold use of their data for ad targeting in exchange for a monthly fee – a model that has faced several challenges from privacy and consumer advocates.

Meta has long profited from selling user data to advertisers but this business model has led to multiple battles with EU regulators over data privacy.

The latest announcement came after the data protection authorities of The Netherlands, Norway and the German state of Hamburg went to the EDPB for an opinion regarding the pay-or-consent model used by Meta.

All digital platforms must comply with the European Union's mammoth general data protection regulation (GDPR), which has been at the root of EU court cases against Meta.

The EDPB in its opinion argued that Meta's model was at odds with the GDPR's requirement that consent for data use must be freely given.

"In most cases, it will not be possible for large online platforms to comply with the requirements for valid consent if they confront users only with a binary choice between consenting to processing of personal data for behavioural advertising purposes and paying a fee," the opinion read.

The EDPB also warned the type of subscription service put forward by Meta "should not be the default way forward" for platforms.

It suggested that platforms should consider an alternative that would give users the right to reject being tracked for advertising purposes without the need to pay. (AFP)
