The corporate reckoning will only come if there's actual consequences for any of this. There haven't been any when this was happening to one big company a month, there won't be any when it starts happening to five big companies a day.
Eg. recent Albert Heijn (Dutch supermarket chain) "cyber incident" must have cost them 10s of millions of Euros.
That's real gain for any competitor NOT having such issue. See eg. Darwinian evolution on how even small (dis)advantages can lead to species being outcompeted & disappearing.
