Whatsapp's in-app notification regarding the TOS change references an EU ruling, so this is the likely cause.

That seems to be a decision by the commission, not the the high court.

These two bodies tend to counter each other a lot, I would expect to have a court ruling in 2 years that cancels this decision.

On this particular subject, it's basically realpolitik.

Court: "US law is incompatible with ours"

Executive: "Yeah but I'm sure we can all get along <wink wink>..."

And then shrems III happens because it's clearly illegal.

The commission accepted the new treaty. No rulings yet afaik: we will see how long this lives.

What does this mean for customers of Meta, Microsoft, and PayPal? Are we consenting to having our data more carefully handled?
