Within hours of new GDPR data protection law taking effect, complaints have been filed against Facebook, Google, Instagram and WhatsApp.

The companies are accused of forcing users to consent to targeted advertising to use the services.

Privacy group noyb.eu led by activist Max Schrems said people were not being given a "free choice".

If the complaints are upheld, the websites may be forced to change how they operate, and they could be fined.
