That's true. Laws about ex post facto are pesky, especially when there's a dire need to address a massive oversight of harm. I almost wonder if there'd be value in government subsidizing the return of old phones to ensure they're disposed of properly, and maintain the simplicity of a return system, but I don't know if the cost of that program would be on the scale of "government budget rounding error" or "defense spending on the F-35".
