Re: GDPR
What, that sweet, sweet valuable data?
Spare a thought for poor MAG. Whether it's landing fees, headers on services rendered to operators such as baggage handling, government subsidies, retail space where you're charged £4 for a bottle of water, operator fees and/or per passenger overheads. They're evidently not making enough money and need *another* avenue to do so by selling your email address. It just so happens here that the process has happened exactly as it would without the hack, but that MAG didn't receive any funds for it and can't provide a thinly-veiled vetting excuse to someone like the ICO as to the legitimacy of the purchaser.
To their plus, it does not mean that there's plausible deniability that anywhere to which they've sold your data and the recipients of the "hacked" data are so mixed, that it's impossible for those that have purchased the data and used it for nefarious purposes to create a blame issue for MAG. If I were a conspiracy theorist, I'd suggest that this is a net positive for them: the ICO are going to chocolate-fireguard any possible outcome; passengers aren't going to choose to drive to "London-Bournemouth-Southend" (or whatever they're calling it this week) instead; the general public is still going to need WiFi in departures so they're not going to lose the data stream; the public will have forgotten by Tuesday; and it's now mostly impossible to tell between any sale/use of data or that resulting from the hack.
I'm sure they're very, *very* """sorry""", for whatever that means.
