General Court endorses the gateway rebuttal that kept Edge out of the DMA

Anyone who has set up a Windows laptop knows the sequence. You open Edge once, type the name of another browser, install that, and go back to Edge rarely. Opera built its case on the first step, telling the court that Edge is "the gatekeeper through which users on Windows must pass to download" a rival, and that this holds regardless of how many users stay afterwards ^[7]. The argument the Commission accepted was about the second step, whether Edge is an important gateway for businesses to reach European consumers ^[4]. What the court quoted was neither usage story but a standard of review: the Commission "did not err by accepting Microsoft's sufficiently substantiated arguments" ^[3].

That phrase is the operative one for anyone planning a compliance budget. Count the outcomes of the February 2024 round on Microsoft: Windows and LinkedIn designated, Edge, Bing and Microsoft Advertising not ^[4][5]. Three of the five services examined came out undesignated ^[20]. The presumption that comes with the quantitative thresholds is rebuttable in practice, not just on paper, and Apple and Microsoft both worked that route in the same round with iMessage and Bing ^[11].

The court has now backed the regulator in both directions. Apple lost its challenge to being designated ^[13], and Opera has lost its challenge to a service not being designated ^[14]. Whichever side of the line the Commission puts you on, plan on it holding.

So the useful grid has two axes. First, do you cross the user thresholds. Second, can you evidence what happens after a user touches your product, in a form a case handler will accept. Cross and can evidence, and your work is the file, built before the market investigation opens rather than during it. Cross and cannot evidence, and the honest budget line is uninstallation, third-party defaults and the end of self-preferencing, with a 10% of global turnover ceiling behind serious breaches ^[9]. Sit below the thresholds and you are still in the top row eventually, because growth moves you there; the file you have not started is the one you will need. The tradeoff in taking the rebuttal path is that you hand Brussels your own usage data and spend a market-investigation cycle on it, and a failed rebuttal leaves you designated anyway with less time to build the remedies.

What the ruling forecloses is the shortcut Opera wanted. Its 2007 complaint over browser bundling produced the EU's ballot screen and, in 2013, a EUR 561m fine when Microsoft quietly dropped it ^[17]; nineteen years on, the newer statute has not been stretched to the desktop the same way ^[21], and the choice screens that reshaped mobile browsing remain a smartphone remedy ^[8]. Opera has not said publicly whether it will appeal, and points of law can go to the Court of Justice within two months and ten days of notification ^[18][19], roughly 71 days ^[22]. Meanwhile the Commission is weighing AWS and Azure for cloud designation ^[15] and has already issued an EUR 890m DMA fine against Google ^[16]. The rebuttal is available to all of them, on the same evidentiary terms.
