I wouldn't refer to getting hacked as a scandal. Unless it comes out that there was some sort of coverup, it seems innapropriate to refer to it as a -gate.
It's a tad conspiratorial, but I suspect there was a concerted effort by media to muddy down the impacts of future watergate-level scandals by highlighting a lot of minor "gates". Already I feel tempted to roll my eyes each time I see another HN post about X-gate, seeing many "weaker" stories using the same nomenclature certainly steals power away from the stories that hit hard.
