Why are they not fining Amazon? Plenty of times bought something that obviously was dangerous when inspected more closely and if you posted a bad review, you got threats (e.g. seller would say I know your address, take down the review or else). Report to Amazon would achieve nothing. But I guess if Temu was running government infrastructure they would be off the hook too.
