The first time my DH and I went to Orlando, we went golfing. When we were in the pro-shop, we were told to "watch the rough on the sixth hole. If the ball goes off the fairway, don't search for it at there is a resident alligator!" 
I couldn't tell if he was serious or not, but I think I stayed in the cart during that hole!
We've seen alligators several times, in several water bodies, including at WDW. However, I would never have expected something like what happened recently to happen. Truly a tragedy, and I cannot imagine how the family is dealing with everything that has happened.
I don't believe that there is a single element responsible...it's a terrible outcome for an activity that has probably happened thousands of times before.
People feeding alligators WILL change animal behavior, and lead to an increase in human wildlife conflict. I can't see Disney continuing to let this behaviour slide going forward.
Just because it's a "magical place" doesn't mean that Disney shouldn't advise people of risks, and allow illegal behaviour. Many people are far removed from nature now, and don't have an idea how to behave, or even what to expect from wildlife. Improving signage will hopefully help visitors think about risks.
