Earlier quoted context omitted.
Taking it up after it became available is not the same thing as asking for it. Sorry but this a frivolous cosmetic thing compared to security issues like Signal's ongoing linkage to phone numbers.
That is correct, but "nobody was asking for stickers" isn't, and that sort of thing does dramatically affect adoption. Also, in the cases I am talking about, not using an app because it doesn't have a feature technically does mean they didn't request the feature, but I'm not sure that is a useful distinction if our goal is to get people to use more secure methods of communication.
I really can't buy the proposition that demand for stickers outweighed the years-long pain points about things like your Signal identity being tied to your phone number or a ping going out to everyone in a person's address book who already used signal, both of which are at odds with the core mission of secure and private communications.
