So which efforts are leading the pack at this stage that I could recommend to my entire family who practically daily urge me to join them on Viber? Years ago I would have said Skype. Now I just don't know. I'm saddened because I thought Telegram looked pretty sweet and a serious new contender. Practically calling them liars after that much hard work is unfair.
How is it unfair? It's essentially factual. They make tons of strange decisions, using things known to be broken, then hand wave over it with "you don't understand" and "ACM champions".
Things aren't fair. Hard work does not automatically grant your result any status.
You know what's also unfair? Pitching a product that's supposed to do something but doesn't.
If none of the available options are acceptably secure, it doesn't do anyone any favors to point to the one that's least broken and tell them to use that. That just leads to people putting sensitive information into a tool that can't protect it. It's better for everyone to just say that there is no secure choice currently and leave it at that.
