To my knowledge, it hasn't, but that's not the main point of my comment so much as expressing my distrust of the parent company. In that respect, no, I'm not aiming to make a claim that Meta/Facebook have had to disclose messages from WhatsApp to law enforcement and essentially undermine its end-to-end-encryption.

Nevertheless, I think it's reasonable and fair to be suspicious of Meta/Facebook given its history of questionable actions concerning people's data. They're in the business of using people's data for marketing/advertising purposes, not safeguarding it, after all.
