The quantity in an individual device is likely to be so tiny (milligrams) that it's not a risk. It's also likely to have been melted down and put through the global recycling chain which would have substantially diluted it. But it was a risk to people handling the original material in bulk. An unknown number of workers in the global copper supply and recycling chain were likely exposed to above-limit doses. A lot of materials safety concerns are more for protection of workers than end users. Lead removal from electronics is an example. There's not really any risk to owning electronics with lead in them unless you are incinerating them or enjoy licking circuit boards, but it is a serious occupational risk to factory workers and also a disposal problem.
