That’s weird. I was there last summer, unaware of such law and brought all my equipment, 2 DSLRs, 2 telephoto lenses, tilt-shift lens, wide angle lens, normal zoom lens and a video camera. I didn’t get stopped anywhere from shooting. I walked with my video camera shooting on the streets and no one has said anything to me. Antiquity sites had a sign to pay extra for taking photos with anything other than a phone, and I paid few times and other times I just declined and could go and see the site with all my equipment with me. In Alexandria in catacombs I had to leave my my backpack with the security guard. They put it in a locker and gave me a key. I was in Egypt for 5 weeks including Sinai Peninsula and haven’t encounter any issues, so I find this whole article surprising.
