A few days later Commission EVP and competition chief Margrethe Vestager warned the company its offer wasn't good enough. The EU is still considering industry feedback on Amazon's commitments so it remains to be seen where that pan-EU antitrust procedure will land. This summer the U.K.'s Competition and Markets Authority also announced its own investigation into Amazon's marketplace — although it's a few years behind so still has to do the work of determining whether Amazon has a dominant position in the market and, only if it confirms that's the case, look at whether it's abusing that position and distorting competition by giving an unfair advantage to its own retail business or sellers using its services vs third party sellers who aren't. So the U.K. is lagging other European regulators in scrutiny of Amazon. Outside Europe, Amazon is fighting antitrust accusations — and lawsuits — on home soil too after years of increasing scrutiny by U.S. lawmakers on Big Tech's market power.
