> what is Meta doing to get around Apple's iOS privacy protections?

Money always finds a way. Everyone thought the changes made a few years ago would hurt Meta but they make $70 billion net profit. At a minimum, they only need a good relationship with advertisers, and a (sort of measurable) increase from a campaign. Also ads are different now. One address may see the same five seconds of an ad hundreds of times. That is a much easier ecosystem to correlate targets through data enrichment.
