“Japan's move follows a trend of international legislative efforts aimed at regulating the dominance of major tech companies. The European Union's Digital Markets Act (DMA) and the UK's Digital Markets, Competition and Consumers Bill are similar initiatives designed to foster competition and prevent monopolistic practices.

Whether it's a "requirement" shouldn't be the metric, the nature and capabilities of it should. If the device can reasonably support customer choice and competition, it should.
