There are somethings to worry about here, but the biggest red flag is the motivation. Buying someone you barely know a gift “so they can match” screams manipulation and control.

Buying a brand new friend a new phone because theirs broke? Cool I guess. Buying a new friend a new phone so they can look like you? That sets off alarm bells in my head and I’d have a serious talk with your kid about boundaries and power and control dybamics.
