A lot of FUD articles use that word, and your first link is probably the most factual. But FYI the only Tupperware products that have had BPA are those made using polycarbonate (PC), which is a hard and brittle plastic very different from most of their products and not the first to come to mind upon mention of the brand; on the other hand, the semi-flexible containers they're most known for are PE/PP, which don't require plasticisers at all.
