The concerns we have are these: Who has access to the data? Where does the data reside? How easy is it for the host nation to get access to the data? That is what we are asking. Everybody who uses a social media app should ask themselves those questions in order to be a better-informed user of social media. In the case of TikTok, if the data is hosted in China, that would be a concern, considering some of China's permissive laws for getting access to user data.
We want Canadians to ask those tough questions about security settings in order to be better-informed consumers.
