Sure they do. But how this go together with security awareness? We are talking about a different market here and as I've posted somewhere else: sure we can have all that trendy crap in there at some point but please don't move that BEFORE the bigger issues out there. Let's not forget that we are talking about a free app here. If this app is being developed with an eye on monetizing at some point, chances are it will become insecure with that and just join the rows of chat apps out there already covering all that trending features. Which will lead to a different app covering the needs of people who use Signal today because they need secure messaging not another app with dancing puppies.
