Columbia couldn't have prepared for the protests it's facing. It was inevitable that the protests would affect the University's operations. To be fair Columbia seemed slow before the protests broke out, but once they did I understood completely why there was a delay. The waitlist letter's went out on the 10th with a week deadline for a reply. This forum will likely light up on 5/18 and after once Columbia knows who is still available for admission. If not a lot of people reserve a waitlist spot, I could see a second round of waitlist offers coming. But to be realistic, if you are not currently on the waitlist your chance of admission is near zero, sorry to whoever is in that camp.
