why are people suddenly talking about cancer risk w Ouisa tirz?

sorry ANOTHER zappy/ouisa post but genuinely curious? i am aware of the situation and am one of the unfortunate people who stockpiled w them. but ive seen like 5 comments today about people suddenly speculating that Ouisa bottles could contain carcinogens? did i totally miss something or are we fear mongering to the absolute max here?

i understand we don’t know where these bottles came from but like it seems kind of crazy to just assume there could be cancerous risk? in theory, sure, i guess they could, but it just seems like such an extreme speculation without anything to go off of. let me know if im missing something here.
