What commenters say

• Some commenters question the effectiveness of the blur feature in protecting privacy, citing the possibility of reversing blur with advanced technology.
• Others argue that certain types of blurs, such as Gaussian blur, can be reversed, but the large blur radius used by Signal makes it difficult to recover the original image.
• The discussion also touches on the security and privacy of various messaging apps, with some recommending Signal, Matrix, and Threema for their end-to-end encryption and self-hosting capabilities.
• Some commenters express concerns about the potential for companies to compromise user privacy, even if they claim to prioritize security and encryption.
• There is a debate about the trade-offs between convenience, security, and privacy in messaging apps, with some arguing that self-hosted solutions are more secure but less user-friendly.
• The importance of documentation and transparency is highlighted, with some commenters noting that Signal's server code is open-source but poorly documented.
• The use of Tor and other privacy-preserving technologies is also discussed as a way to enhance security and anonymity online.
