I am ok with it being below maximum for now.
They should start to increase the fines little by little and the big corps will caught on and start to treat the security with more respect.
If they make no attempt to improve their security I suspect the next incident will cost them $800m. Be interesting to see who will insure them against that.
When the parent comment said "they could set up an insurance fund", I believe they didn't mean a literal contract with an insurance company, but a straight up savings fund set up by Marriott to be used in the future specifically for expenses like that.
