50% doesn’t suport that at all. It’s literally half.
What? Let me recap the discussion:
1. Article states that Apple threatens to pull iMessage and FaceTime.
2. Some people argue that this would not have a big impact, because these two platforms are not so exclusively dominant in UK (or Europe), and that many people already use WhatsApp.
3. If iMessage and FaceTime were to be pulled, people would quickly and easily switch to WhatsApp.
Guy presents stats to argue:
1. Confirms that only 50% even have access to iMessage and FaceTime today.
2. States that WhatsApp used to be dominant, but is losing share (although may still be dominant, he does not clarify this).
3. At 50% iOS marketshare, we know that pretty much all of these 50% also have WhatsApp installed and many use is at least occasionally to communicate with the 50% that don't have iOS or for Group Chats - no one initiates a Group Chat on iMessage.
Hence, Guy's argument supports that iOS users would instantly swap to WhatsApp if iOS and FaceTime were to be pulled. The pain suffered would be minimal.
