I'll probably get down voted to hell, but this seems to be quite overblown.
The FDA has posted their latest analysis of J&J talcum powder.[1] Of the 3 samples, 1 had "none detected" and 2 had 0.00002% or less by TEM (electron microscope). We're talking close to limit of detection.
The bigger issue is the link to ovarian cancer. The data is all over the place. This one paper [1] sums up the data nicely - when looking at talc use there was no correlation with ovarian cancer. Even outside of hygienic use (condoms, gloves), many women had high talc exposure and no ovarian cancer, while others had no talc exposure and ovarian cancer.
"It may be argued that the overall null findings associated with talc-dusted diaphragms and condom use is more convincing evidence for a lack of a carcinogenic effect, especially given the lack of an established correlation between perineal dusting frequency and ovarian tissue talc concentrations and the lack of a consistent dose-response relationship with ovarian cancer risk."
