While Signal has substantial problems, to my knowledge this “tracking” has always been non-technical. It is having access to someone’s unlocked phone and therefore being able to see the messages on it. Most apps will have this kind of weakness, even high quality open source security ones, and most of the security weakness is social: don’t put things in a chat that that would be bad news if it was screenshotted or leaked by a disgruntled or careless member. Infiltration is also possible but pissy babies and incompetence are more common. Don’t even put anything spicy on any chat unless it can be a one-way untraceable blast or something. Rely on irl face to face organizing as much as possible. It’s better anyways 99% of the time.
