@aronkvh @mattburgess The conversation will work like this:
"Hey, I sent you that WhatsApp"
"yeah what was that about?"
"I used a new function in WhatsApp"
"but I'm not using WhatsApp, I'm using <insert different app here>"
"oh, that's inconvenient. Can you maybe just switch to WhatsApp instead?"
Interoperability barely works when all parties have common goals and good intentions. I do not assume meta to have good intentions.
@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.
