I do not work for or speak for OWS, but that said...

When Signal first launched, the push notification handler just displayed
"New Message". This is annoying from a UX standpoint.

I believe they later added support for decrypting messages within Signal's
push notification handler.

I believe it's also an option you can toggle on and off (so as to e.g.
prevent someone who steals your phone from seeing these messages)
