Here's my wild speculation..

Sybil and VITAS connections.
The relationship of VITAS to the sybil: virus is such;
The discovery of the Awakened and their subsequent labeling as a'threat' caused the
Matrix development to take on a sinister path.
Example:The AI infiltrations of the
Matrix are not that, but engineered process to push development of the matrix therefore the pushing the userbase development. A simular 'infection' protocol is necessary for both. So VITAS was born for the purpose of defining a suitable 'userbase' by eliminating unfit subjects.
The Sybil vector was to further make the
Matrix userbase more acceptable hense the inorganic infection schedule...
