And you can't, with a straight face, tell me that lead free solder matters, while we're still using lead acid batteries with dozens of pounds of lead in every car out there (to within a rounding error, and, yes, it includes almost all EV/PHEVs). The list of exemptions is very long.
Lead free solder is objectively worse as a solder for just about any metric related to longevity. So you have to weigh the risks of lead in solder against the reduced longevity of entire electronic devices from solder joint failures. Lots of BGA components have had problems related to their solder, and the usual result is that the entire device gets thrown out.
