These are mostly class action suits that will result in a settlement. Antitrust enforcement in America usually just means the company will sell some of its divisons (maybe Google sells the ad business). Half the push for tech regulation comes from Republicans looking to "own" the Democrats. This EU law would not fly at all in America.
Tech regulation is coming from both sides of the aisle. The FTC is under the chairmanship of Lina Khan, who cut her teeth as an Amazon critic. Democrats are hugely concerned about the app company platforms permitting tracking of user personal information, especially in the aftermath of Dobbs. (I suppose you said "Half the push", which is accurate as there are bipartisan grievances against Big Tech.) America might not pass a law as comprehensive as this one, but it certainly looks like the regulatory environment is inching towards that direction than ever before. The times, they are a-changing.
