Over the past days, two popular chat services have accused each other of having undisclosed government ties. According to Signal president Meredith Whittaker, Telegram is not only “notoriously insecure” but also “routinely cooperates with governments behind the scenes.” Telegram founder Pavel Durov, on the other hand, claims that “the US government spent $3M to build Signal’s encryption” and Signal’s current leaders are “activists used by the US state department for regime change abroad.”
both suck when it comes to real hardcore privacy! Signal is surely a bit more private/secure/whatever, unless maybe you count in the US jurisdiction.
if you want hardcore privacy and security, use SimpleX. it’s cutting edge.
