What happened in Tanisha's father's that caused him to give her the camera

I think it's: He wants her to have a hobby because she spends too much time on social media.

B/c in the passage it says: Tanisha loved taking pictures with her mobile phone and posted regularly on her social media sites. The camera was pretty good even though it was already a few years old. Hundreds of photos of her and her friends had filled the daily stream over the past year, the first year she was allowed to have an account. She occasionally took photos of other things like her cat, Hubble, and hamster, Mr. Lincoln. But most of her pictures were of Tanisha and whomever she was hanging out with that day.
