Yelled at my family during a dinner party

For context, my family and I have never gotten along. They spent my entire childhood controlling everything I did, even what I ate, drank, and even they chose for me not to have friends. And then, I was married off to a good man, thank god for that! 

Now I have a kid and I don’t want her to live the same life as I did so I have been giving her the freedom that she needs to grow as a better person, unlike her grandparents and uncle (my brother). She can do whatever she wants and can be friends with as many friends as she wants and I am really glad to see her happy. She is enjoying her childhood in the best way possible. 

I had been playing Star Chef 2 since the day it started because it's really difficult for me to make friends courtesy of my family. See, I am giving you the right reasons to hate my family. Now, even my baby plays the game because she loves cooking, and baking and she also helps in the kitchen (of course, she doesn’t know what she is doing, but she loves the colors around) which is something to be proud of as a parent, you know.

The issue arises here. My parents invited us for a family dinner and my husband, being the humble human that he is, agreed to join in the celebrations with them. Honestly, I didn’t even want to go through the usual nonsense like eat this, sit here but then I went. I made sure I was seated a little far from them with my baby. My daughter isn't used to such celebratory events so she was playing the game. Being an ungrateful uncle, my brother snatched the phone screaming at her saying that it isn’t the right place to play. I lost my cool and screamed at him at this crowded restaurant. 

Who is he to control my daughter? If I, being the mother, did not think twice to give her the game, why is he controlling her in a crowded restaurant? It pisses me off that they are trying to control her just like they controlled me. Haven’t they seen me go through these situations before? 

The topic went off somewhere else and my brother gave me some fatherly advice to stay away from them and told me that I have been a pain all my life. Also, they thought I had lost my mind since I blasted out in a restaurant which seems not fair but I had to. I guess I should have held it in and dealt with it later but I've had to let this anger out someday and it was this day. Am I wrong? I am not sure if I am right or wrong at this point. Please tell me what do I do in this situation.
