Meta would have a field day with this change, since it was the company that was most upset and angry when ATT was introduced.
Considering that ATT was about sharing an identifier to “track across other companies' apps and websites” (text definition of the ATT setting), I don’t believe this ruling is a good move for anyone on informed consent or privacy. In the name of improving competition, sometimes regulators may end up making things worse for users.
Meta, the same company that used to play silent audio so it wouldn't be killed in the background? I'm not super worried about them being upset about privacy laws changing.
