The European Commission has launched five noncompliance probes into American tech giants Apple, Meta and Alphabet—the bloc’s first investigations under its newly-implemented Digital Markets Act.

As major tech companies, particularly Apple, face increased regulatory scrutiny around the world, the Commission’s probes, announced Monday, will look into whether Apple and Google-owner Alphabet unfairly favor their own app stores and whether what regulators call Meta’s “pay or consent” subscription model violates the new act.
