First of all, thanks for sharing because it's such an insightful paper!

Some thoughts/doubts on it:

1. It's unbelievable that in a world where we promote privacy and freedom of individuals such cross-country trackers exist. It seems more an Orwellian story rather than reality.

2. I'm a bit ignorant on this theme on a technical level (I have a business background, even if working at a tech startup focused on security). There is a growing concern globally over an increasing sensitisation over privacy and over the importance of security. Even Google has promised to remove third party cookies within 2 years, and there is going to be a migration from Whatsapp to Signal (even if Whatsapp clarified a bit on that). Do you think that such fresh tools like these "favicons" or simple tracking will remain long term?

Do you speak Spanish by any chance? The way that you are using "doubts" (dudas) sounds slightly off to me. I live in Spain and I hear it a lot :)
