While a lot of the items they bring up are legitimate issues, almost all of them are issues universal to any messenger application. They don't offer any real solutions to these issues, so I wasn't sure what they purpose of this article was then, until I got to the bottom and sure enough they have their own alternative they're wanting to pitch to you.
Extreme claims require extreme evidence. The claim they have is that they were targeted directly, and signals encryption was broken (or signal elected to steal the data?)
I've never heard of these people or their "legacy chat application" that would be worthy of compromising signal. And they are trying to sell their chat application bundled on a VPN as "airgapped" from the internet.
"There is a better way to handle this and that’s to use invitations sent by users. You can only connect to someone who invites you. There is zero spam and no need to validate email or phones, since you send your invitation to the email or phone number you personally know."
This does not seem like a robust solution. Also if you think of social networks as a network graph, then this seriously limits reach as you heavily rely on key folks who are a part of multiple networks of friends to invite those friends, etc which makes it really hard to scale. Any workaround to that problem, will inevitably introduce access for scammers.
Honestly, it’s gotta work across all my devices pretty well. Signal doesn’t really let you move from device to device easily. I like privacy, but I don’t need it that badly. If it had a chat history, I would pay for it to be honest.
The problem with Signal and Proton is they sacrifice usability for over the top security. I don’t want to use Google or Zuckerberg products that are using you to sell ads, but I don’t want terrible usability either.
