From the article: "Recently, Meta told EU regulators that making this change represented a "significant hurdle" for Meta and noted that it will "require at least three months to implement," the WSJ reported. That's why it seems like making the update by the end of October might be an ambitious deadline."

Looks, like EU gave them a deadline for end of October to implement the change.

The offsite tracking is really bad. Best we can do is report to Datatilsynet.
