Threema is closed source which is something I don't really like when it comes to security as there are no independent audits.
Edit: Generally, Threema seems interesting feature-wise, but I think the price (4€) will prevent my contacts from using it...
Interesting thought experiment though; if you’re not paying for the development and hosting- who is?
threema claims no having no identificable information yet the account IDs are just the unsalted hashes of your telephone number.
Pidgin is exactly what we need.. and each messenger needs to be a pluggable module. Then we dont need to hound friends and family to switch messenger apps they just use pidgin.
But why would something like Facebook open up their walled garden? Does it even count as a walled garden when you have 2 billion people on the platform?
Obviously yes.
Does any wall count if there are more entities on one side of it than the other?
However, all of these bloody messengers mean that my contacts list is spread across a multitude of programs: we need the iOS/Android equivalent of pidgin.
