This is a compelling reason to use Wire over Telegram or whatsapp. I am assuming we can run our own instances though.
i would hope the "not being owned by a datamining advertising giant" of wire or telegram would be a good reason to use them instead of whatsapp.
You should be extremely suspicious of any messaging company that advertises client-server encryption as a privacy feature. It obviously is not.
if I will find only one my contact on Wire, it can be amazing as much they want, but it's useless, reason why I switched today from Hangouts to Facebook Whatsapp as my secondary messenger (primary is Signal), which I really don't like (especially bloated UI with 2 unnecessary tabs out of 4), but there is not really any other option, since nobody use Allo, Skype has horrible UI, and very few people use Telegram or Viber
telegram, wire or signal are fine for people working in IT, but if you have contacts outside your work circle they are pretty much useless
