Linux has a fundamental security problem - it basically tries to protect the system from the user, not the user from himself (other user apps).

So it's difficult to modify a Linux system binary, but it's extremely easy to delete or exfiltrate a user file.

This security model might have made sense in the past, but today it's totally outdated since almost all systems, both local and in the cloud, have a single user which is the owner (has sudo).
