I'm all for protecting the tigers, and perhaps a place like Ranthambhore allows too many tourists in. But this whole thing is crazy. Everyone knows the real threat to tigers is 1) poachers and 2) the occasional villager who gets mad if a tiger is preying on his livestock.
Keeping tourists out only allows more of 1 and 2 to go on. Hopefully, they'll just reduce the numbers allowed in.
