With rising concern about privacy violations and security issues of computer technology giants like GMAFIA, companies and products are now advertising for themselves using the term end-to-end encryption to mislead users.
I’ve always said that end-to-end encryption only works if you’re in control of the encryption secret/public keys, not the product/company. Sadly, many fall into the false claims of tech giants about privacy.
End-to-end encryption supposed to eliminate the ability of middle-man or messaging servers/companies to read the message. Now, if we don’t control our encryption keys and rely on keys that are controlled by the company (messenger provider), there’s no difference with no encryption at all.
Messengers like Facebook Messenger, WhatsApp, Google stuff, etc. are not safe, even with encryption because the company is controlling the keys, thus can read and share our messages, encrypted or not.
I always have suggested libre decentralized messaging software like Matrix and XMPP which can be self-hosted and secured with true end-to-end encryption.
