That's been covered a lot ....
Regardless of which school is chosen, it is strange for a prospect to be publicly expressing anger/bitterness/ridicule towards people who are offering them a scholarship, money and taking an interest in helping them achieve their future career goals.
There have been times when athletes have done this while choosing Tennessee (I remember Vincent Yarbrough in basketball from way back in the day .... while announcing for Tennessee over Kentucky). It makes me cringe, regardless of whether they are picking Tennessee or someone else.
It's not a big deal; nor is it a poor reflection of anyone's character or upbringing, but it is a strange way to act towards people who have taken the time to recruit you.
