Element (or Matrix in general) hasn’t been cut out. The comment might be thinking about https://element.io/blog/element-on-google-play-store but it got reverted after we explained what decentralisation was to Google.

It is true to say that Matrix is more at risk than Signal, though, given Matrix allows for public chatrooms - whereas in Signal you have to invited into whatever abusive content rather than being able to selfinvite (ie join).
