It sounds like there is no lawsuit. No consequences. The other apps are safe lying about using encryption.

To settle the allegations, "Zoom has agreed to a requirement to establish and implement a comprehensive security program, a prohibition on privacy and security misrepresentations

“Zoom is not required to offer redress, refunds, or even notice to its customers that material claims regarding the security of its services were false,”

That’s the message the FTC is giving. The only problem for the FTC is that Zoom admited it lied about encryption. The other apps should never publiclly reveal that they are lying and they should be fine.
