PGP-encrypts the unblock key to trusted recipients so you literally can't disable it yourself.

Strengths

•Netfilter SNI inspection at kernel level means blocks can't be bypassed by user-space tricks.
•PGP mode erases the key from kernel memory — unblocking requires a trusted person to decrypt.
•File hardening with chattr +i and inode_operations overrides re-applied every second.

Weaknesses

•Linux-only with no Windows or macOS support, limiting the addressable market significantly.
•Requires root access and kernel module loading, which some environments restrict or audit heavily.
