the complaints about formulation change or difficulty in deliberately purchasing borosilicate aren’t rumor or fake news, the formulation change is half of what snopes lists as the truth, and that’s exactly what is being claimed above.

the fake news part is china,china,china, and the unresolved part is whether or not this formulation change happened to more than coincide with any sale. which snopes won’t touch, because that could sure get messy without receipts. but isn’t that the root of the rumor?

snopes is to fact checking what fox or cnn are to news. any fact checking is coincidental, and not the primary purpose of the site.
