Staff effectively working for TikTok used TikTok location data to track
reporters to try to find staff who were giving interviews to those reporters.
I don't care whether those staff had asked permission. I don't care
whether TikTok (or its Chinese owners) are sincere in saying they
won't do this again. The problem is that they do collect the data,
and are in a position to use it to track people if they decide to.
The problem is that the system is designed to require users to trust
the good will of the company's staff and management. Such a system
must be designed differently so that users' trust not to track people
is not an issue.
The fact that some Chinese staff could track the locations of US
reporters and their US sources makes the problem additionally grave,
but that is not a fundamental change. Enabling the US staff to track
the locations of people in the US is dangerous too.
