Signal isn’t to blame, but endpoint security and group chat hygiene are still real risks

Meta appears to be reversing its strong stance on encryption. The first obvious casualty is that they’re abandoning and disabling end-to-end encryption in Instagram DMs.

"𝑃ℎ𝑜𝑡𝑜𝐷𝑁𝐴 is unreliable for the detection of illicit content: it is easy to incriminate someone by sending them false content with a hash value close to illicit content (a false positive) and to avoid detection of illicit content with minimal modifications to an image (a false negative)."
