People don't care about their privacy and security until the day they got scammed. And then it's too late already. Privacy and anonymity is still associated with darknet, money laundering, etc. And no one thinks that sharing you phone number and ID scan everywhere can lead to the huge problems.
Hahah, on the contrary, the biggest problem is that users do not think about the security of their data at all. As for the darknet and other things, it seems to me that user information is outdated, at the moment such applications are closely associated with Web applications, which is a new and interesting turn for me.
