Ouch, that's bad news.
I certainly hope, CX does not go the same road of disputable big-data-privacy/business/tax practices as Amazon did and is doing. There are genuine reasons why Amazon is under the magnifier glass, both in the EU and the US. And, the same for that big one in China.
And, without going the Amazon road, this business type is not really that profitable.......
Edit: And, I immediately removed all marketing newsletter subscriptions, as well as all personal information (for CX, MPC and AsiaMiles) not absolutely needed to be able to fly
