Obviously not. Think about supply and demand. Because a toxic product is being hailed as secure there isn't enough demand for an actually anonymous and private messenger. So calling signal "secure" is just helping state security.
If you actually want to message about revolutionary (illegal, "terrorist") activity and don't want to be traced immediately by an agent of state security or an informant, Signal offers nothing (unless you use criminal activity like identity theft). In such a case a warrant will obviously be granted and they can immediately find and arrest you.
Can you see the logic how Signal isn't secure at all for an actual dissident?
Look closely - how does she still looks good for people. She just dedicated her Nobel price to Trump. It might just be conspiracy lol.
It's also indisputably true that the US sponsored coups and engaged in economic warfare for over 20 years, and Machado is right there working with the US against Venezuela. How is that peace? So, how DOES she look good? Is it something with your eyes? Or maybe with the words you read that you allow to program your mind? Like brainwashing? Like, how even the Nobel committee thinks she is a good person? How can people have a good opinion with her?
And more importantly, how can you have a democracy when people are this brainwashed? How do you defend against it? How should Venezuela defend itself against this hybrid war?
