This is increasingly my suspicion. I'd expect that they could have solved any technical issues around disabling tracking or letting users opt-in/out by now, which leads me to suspect that they have their business model based on being able to share certain data. It's very possible that they've A/B tested GDPR compliant flows/messaging, and found that their metrics/revenue dropped enough that they feel they have to do something more drastic. Although the argument against that is the fact they have literally just disabled access for European users.
