This might be able to answer your question. From
https://www.henrymakow.com/why_do_the_illuminati_reveal_t.html
Why expose themselves? Why not operate in complete secrecy, performing the coup de grace from behind a curtain, leading up to a final and totally unforeseen blow, culminating in total assumption of power?
The answer is partly to be found in
Portisch's article about German ID's: to "make the people afraid" (but NOT to "impress them").
The Illuminati have characterized themselves as wolves among sheep. They are proud of this self-description and they hold to it.
Predators stalk their prey. They do not simply move in and take the kill.
Whiffs of the scent of the stalker are permitted. Shades, shadows, unnerving shifts of position...the prey gets spooked.
The generation of adrenalin overpowers reason. The prey can sense the oncoming attack. Panic besets the prey, during the moments of final approach. Defensive tactics are forgotten, as panic takes over. The prey makes a wild race for the exit, but the predators have already encircled every possible exit.
The Illuminati see themselves as wolves stalking the sheep. They let out whiffs of their scent, generate shadows, perform deceptive motions, and generally aim to spook the prey. The kill has yet to come.
'REVENGE'
There is another reason.
The core Illuminati group have, for at least two thousand years, felt themselves engaged in a bitter vendetta amounting essentially to a blood-feud.
The Illuminati do not see themselves merely as assuming power, but taking BACK what they consider their rightful place and their natural property: being in control of Human Destiny. In their minds, Human history is, and long has been, an issue of war.
The unexpected emergence of Christianity foisted -- or at least very seriously delayed -- a number of Illuminati plans. The accession of Christianity as a major social and political force spiraled out of control so rapidly that the comparatively small numbers of the ancient Illuminati were driven into hiding and secrecy. From this, the blood-feud -- the Vendetta -- emerged.
When the Illuminati publish their presence, it is not so that "normal" people can detect the symbols and formulate what most would see as spectacular conspiracy theories. It is an announcement of expectations of victory, in the manner of a vendetta.
When the Illuminati announce their influence, it is meant to be the voicing of a threat to their enemies and their prey. "We have established yet another foothold. We are coming for you, in due time."
