"Someone posing as a Ukrainian citizen just joins the chat and starts spreading misinformation, or gathers data, like the location of shelters," Tsekhanovska said, noting how false messages have urged Ukrainians to turn off their phones at a specific time of night, citing cybersafety. But because group chats and the channel features are not end-to-end encrypted, Galperin said user privacy is potentially under threat. False news often spreads via public groups, or chats, with potentially fatal effects. If you initiate a Secret Chat, however, then these communications are end-to-end encrypted and are tied to the device you are using. That means itβs less convenient to access them across multiple platforms, but you are at far less risk of snooping. Back in the day, Secret Chats received some praise from the EFF, but the fact that its standard system isnβt as secure earned it some criticism. If youβre looking for something that is considered more reliable by privacy advocates, then Signal is the EFFβs preferred platform, although that too is not without some caveats. The next bit isnβt clear, but Durov reportedly claimed that his resignation, dated March 21st, was an April Foolsβ prank. TechCrunch implies that it was a matter of principle, but itβs hard to be clear on the wheres, whos and whys. Similarly, on April 17th, the Moscow Times quoted Durov as saying that he quit the company after being pressured to reveal account details about Ukrainians protesting the then-president Viktor Yanukovych.
