Morphology
The meaning is directly derivable from 'floodgate' (a barrier holding back a large flow) plus 'opened' — removing a restraint leads to a sudden outpouring. This barrier-release metaphor is straightforward and cross-linguistically common, so a B1 learner who knows the constituents can infer the intended sense.
Etymology
The phrase floodgate opened comes from a simple picture: a gate that holds back water. When the floodgate is opened, a large rush of water pours out, so the phrase means that when a barrier is removed there is a 'sudden, out of control flow' of things like applications, criticism, or emotions.
