After major security vulnerabilities or data breaches, "security people" show up and tell you to delete your account immediately. "Oh, time to delete your account! Switch to service/product … instead!"
Such statements totally ignore that security vulnerabilities are widespread and the vast majority of data breaches won't become publicly-known. Full control over your data and devices requires 100% isolation from the internet, not just arbitrarily switching services or products.
OTOH one could very reasonably say that, say, signal is better than Facebook from a privacy and security standpoint.
@infosechandbook yeah, rather then pointing at what people should use, we are better of educating people why one would want to use a service or why not.
You can accidentally leak your private GPG key, or the endpoints of end-to-end encryption can be compromised. GPG also offers no perfect forward secrecy. An attacker can just record encrypted data, and may have the ability to decrypt everything in future.
As @Bobo_PK suggested, cryptographic algorithms change over time. Years ago, DES was considered secure …
