The Church has never denied the possibility of Limbo as it has been variously described, if that is what you were thinking. I am not aware of an “uproar” over such speculation; it may be more like “murmuring and grumbling” by some who choose to disagree with the postulations.
I would prefer an “uproar” over the clear and enduring heresies that the dead automatically enjoy Heaven, and the implication that they are somehow not in need of prayers, or funeral rites, or reverent disposition of their remains. It is clearly the work of Satan, who does not want us to repent, that so few people believe in the very realities of Purgatory and Hell.
