According to TechFlow, the exclusivity of ownership is particularly evident in assets, which is why cryptocurrencies are closely integrated with finance. However, the understanding of data ownership is not clear. Supporters of data ownership often mention big tech companies, saying that they are manipulating us and pushing ads to us, etc., but this is not an argument for "owning your own data." The real problem is that you can't choose different algorithms. Every major platform is actually restricted to a single algorithm, and they keep changing it. This is more like one of the following two arguments: make laws that force algorithms to be open/flexible/bring your own algorithms; data is open so that third-party developers can access the data. The key is not "ownership" but third-party access rights. This does not mean that there is no sensitive information in the data. Obviously, financial and medical data are sensitive. There are clear standards today to export data from electronic medical record (EMR) systems to patients so that they can have a copy.
