So, TikTok on my (Android) phone has a grand total of zero permissions. And even if it is able to download and run some code, isn't it running in a sandbox? I don't really understand the panic here...
While the app might not be able to harm your phone, your grandma or daughter might not be as tech savvy and grant permissions more freely. Also, even though sandboxed, if you can download and run u known code on the devices of billions of users, you have a very large phone-botnet at your disposal of you ever need it
Even if it wasn't your intention, it sounds like you're implying tech savvyness is exclusive to men...please try to be inclusive, this industry needs it so much.
