@claudius @aronkvh @mattburgess fail to see how this should make people who even refused to use WhatsApp while it wasn't interoperable *at all* to switch to it. 3E doesn't work just because you hope or fear it will. I do not see any plausible path to success here.
@hllizi @aronkvh @mattburgess I have seen this pattern with XMPP on Facebook chat.
I have seen this with people asking other people to get on Gmail (because gmail -> gmail end up in spam less often (I wonder why!? /s))
Heck I've seen this with Funny SMS ASCII-images that only worked correctly on other Nokia phones.
I don't really care if you don't find it plausible.
