Donald Trump supporters embrace Signal, Telegram and other 'free speech' apps

What else would you expect people to do once you start showing them the door?

If you are worried about deplatforming, why move to an app with the same issue? They should move to xmpp and then Trump (or whoever the thought leaders are) could pay for their own server.

Although I do wonder how that would look after the issue with Hillary's private server ;)

And so does everyone else who values their privacy. The issue with Whatsapp is about trust and peripherally, if at all, about Trump.
