Meta warned Wednesday that European users could face a "materially worse" experience following a key regulatory decision by the European Commission, BBC reported.

Meta recently introduced a "consent or pay" model which leaves users to choose between paying for a monthly subscription or letting Meta combine data it has collected on Facebook and Instagram.

Last week, the European Commision - the EU's executive - announced it had decided that the model does not comply with the Digital Markets Act (DMA) and fined Meta €200m (£171m).

"Based on feedback from the EC in connection with the DMA, we expect we will need to make some modifications to our model," Meta said in its quarterly earnings statement, according to BBC.
