I'd imagine that Signal's increase in popularity is overwhelmingly due to WhatsApp's recent changes to their privacy policy rather than Parler's shutdown. More of my contacts have joined Signal in the last week than they had in the last year. I'd be surprised if any of them were ex-Parler users. Parler was pretty much the antithesis of end to end encrypted and secure, and Signal serves a very different purpose to Parler. From what I've seen on Parler, their average user would dismiss Signal as being produced by commies and therefore evil, due to its Open Source license.
