Short version: I strongly do not recommend using any of these providers. You are, of course, free to use whatever you like. My TL;DR advice: Roll your own and use Algo or Streisand. For messaging & voice, use Signal. For increasing anonymity, use Tor Browser for desktop, and Onion Browser for mobile.
