Explanation: the toggle to opt out is made available after you log into Google and you must navigate in multiple screens which gives Google ample time to collect hundreds of contact details. Of course, it is not possible to turn on airplane mode during this procedure since the log in requires an Internet connection.
This is 100% against the EU GDPR. I've submitted a complaint to my local privacy regular (French CNIL) but never heard back.
This probably impacts 200+ hundreds millions of EU citizens (since 2/3 of the population must be using an Android phone). I can't imagine a more massive data collection program, since each user must probably have more than 50 people on their device so the total amount of people that is affected exceeds my imagination.
How can Google get such a pass?
