Hmm, not sure these examples make much sense here. Yes Twitter is losing popularity and WhatsApp is gaining it, but remember that: 1. For most people, WhatsApp's key draw isn't privacy or encryption, it's a convenient way of messaging people for free. It's replaced standard text messaging for many of them, and IM clients for others. Similarly, Twitter may be mostly public, but that's not really why people might not be using it so much any more. Instead, I'd blame its continually worsening reputation (associated with mobs, doxing and people getting attacked for 'wrongthink'), general decline in quality due to recent political events taking over everything and poor management that doesn't understand what its users really want from the service. The fact these services can be used to represent 'privacy' or a lack of it is a nice coincidence. 2. The two services aren't really direct competitors. People don't use WhatsApp to replace Twitter or vice versa. It could be more useful to look up what those WhatsApp users were using before switching to the app, and figuring out where Twitter users go after they leave.
