Facebook Nederland B.V. is just one of the defendants; the other defendants are Meta Platforms Ireland (based in Ireland), and Meta Platforms Inc. (the main company, based in the USA)
The Dutch subsidiary has been acquitted, as it only managed advertisement income, not the app design.
Meta Platforms Inc. has been acquitted, as it itself doesn't directly provide apps or services in Europe (nor the Netherlands) - legally that's managed by Meta Platforms Ireland and so not Inc.'s responsibility.
Meta Platforms Ireland has been ordered to implement these changes, enforced by the up to 5 million euro fine (see pages 20 and 21 in the verdict)
I guess they're writing the paperwork to cut off that particular subdivision as we speak.
