I agree that the data is already available, but to hurt the users without a second of hesitation? Much better and justified to go after the company, ... slowly step up the pressure and escalate it gradually until you have their attention. Tag their CxOs on LinkedIn, call them out in person (don't let them hide between a corporate facade) for their greedy negligence. Better would have been by publishing a paper about it imho ... But to hurt the user like this? The author is a flipping coward.
