#CyberSecurity#Privacy#Messaging#Metadata#Encryption: "When stored, aggregated and analyzed, this metadata provides ample information that could potentially incriminate someone or be submitted to authorities. When WhatsApp and Facebook Messenger enabled end-to-end encryption for messages, of course it was a welcome and widely celebrated change. But it’s important to remember that not all end-to-end encryption utilizes the same standards, some implementations are more secure than others, so it’s something that shouldn’t necessarily be accepted at face value. More importantly: collecting and storing an obscene amount of metadata should invite global scrutiny, considering this data is often combined with whatever other information companies like Meta harvest about your identity (which is a lot.)
This is one of the many reasons why we need to resist giving out our phone numbers just to access an app, especially to do something as personal and intimate as private messaging. Even though users can sometimes mask their numbers with a username, their identity on the app is still fundamentally tied to their phone number. App operators have access to this, as well as user contacts. Additionally, with a simple modification to the app's source code, the contacts may also gain access in some cases. This should raise more concerns about privacy, and it makes the need for anonymity difficult to achieve." https://simplex.chat/blog/20240416-dangers-of-metadata-in-messengers.html
