Facebook Announces Messenger Security Features that Don't Compromise Privacy

I wish they’d re-allow cellphone number only Messenger accounts.

You wish to give them your mobile number?

I can get a prepaid number in my second SIM slot in my Lineage phone. Then run a web only messenger account with a few people. Then I swap burner sim cards as needed for each cluster of contacts.

Its sad but I still have normies in my contacts. Unfortunately FB blocks my attempts to create burner accounts.
