You mean DMCA. It is not an antitrust framework. Europe has pretty robust anti-trust framework. DMCA is an attempt to regulate companies that cannot be legally considered monopolies, and that do not run afoul of any pre-existing EU regulation.

Just for that case a new category of business classification was invented: the gatekeepers, and coincidentally almost all of those gatekeepers are American companies. Unlike antitrust regulation and other EU regulation that wan't based on clearly observed harm to the consumers, as otherwise that would have been covered by existing laws. It was solely designed to prevent businesses to have a potential ability to do something anti-consumer.
