CJEU C-252/21: Competition Authorities May Sanction Tech Giants' Privacy Violations

Validated facts

Judgment in the Federal Cartel Office vs. Meta dispute. Competition authorities may, when assessing market abuse, examine whether a group violates the GDPR (merging WhatsApp and Facebook data).

In plain language

Double scrutiny for data octopuses: If Facebook misuses your data, not only the data protection officer can complain — the cartel office can impose fines too.

Security relevance & practical tip

Prevents platform monopolists from ignoring privacy rights with impunity.
