The European Union has confirmed the first six tech "gatekeepers" that will need to abide by strict new rules under the bloc's Digital Markets Act (DMA). The names of these companies should be pretty familiar: Alphabet, Amazon, Apple, ByteDance, Meta and Microsoft. The European Commission (EC), which is the EU's executive branch, noted that after assessing whether certain companies met thresholds related to revenue, valuation and user numbers, Samsung hasn't been designated as a gatekeeper as yet.
