I'm completely unfamiliar with what systems exist, but here's what the article states:

> the White House had authorized the use of Signal, largely because there is no alternative platform to text in real time across different agencies, two people familiar with the matter said.

> Previous administrations, including the Biden White House, did not develop an alternative platform to Signal, one of the people said.

Are you saying these sources are dissembling? Wouldn't surprise me at this point, but just making sure I understand what you're saying.
