@edri 2/2 so not only does this discriminate against those not having a mobile device, or used their choice of running it "tracking free" with a custom ROM and no "store account" – it REQUIRES those using the app to have an account with a US company tracking them via their services.
Objections? Oh, you have something to hide? => stigmatized. Suspect because of valuing your privacy.
And enforcing us to give our data to an US company, outside GDPR directive. Again, violating their own laws.¹
