The tech companies design the system so that there exists no central key that could be used to decrypt every conversation. Each conversation generates their own unique key. If some back door existed, it could never be limited to "law enforcement" any hacker could unlock every conversation. Politicians are incapable of learning this.

And in fact nobody claimed that, at least not in this thread.
It's still not impossible to provide the keys for a conversation, it's not a technical limitation by any means.
Perhaps the good guys at Mullvad can provide that level of privacy, but certainly not WhatsApp, their interest align with those of the users practically never.
