Opinion letter.
None of the accusations in the title can be substantiated, more than a dozen other apps and technologies are backed by the same organization the article mentions funds part of a signal’s budget.
Assertions that TOR has a governmental back door, that the CIA wants people to use Signal, are not substantiated, and the article states at the same time that there are fears the anonymity of Signal threatens western governments. Can’t have it both ways.
The only definitive thing this article can prove or cite is where some OTF funding goes, which was publicly disclosed since it’s inception. It reads like a /r/superstonk GME reeeeeee post equivalent for communication security by a ti foil hat.
