Interesting sunshine, not all symbols represent or are intended for illuminati energy, because the pyramid is symbolic for all people living within this universe, and it is common for people to think badly of this because of how it has been interpreted with modern knowledge seekers, but it holds great energetic power for us all.
I have to say that first up my thoughts are for energy of illuminati nature, yet the thing that stands out is the tip of the pyramid is flat, therefore I would say the top of the pyramid in this case actually has a wider range of leadership, because the illuminati take the tip of the pyramid off and away from the ascending layers, so the illuminati display that they put themselves above.
Your fathers business is working, so why fix something that is not broke! Perhaps you could suggest adding some colors to tone down the black and white, because I agree with you, and this infuses energy of not-negotiable.
