Is it fair that my older brother gets to boss me around just because he's older?

My parents allow him to tell me what to do and I am so sick of. We have a kind of big age difference. I'm 15 and he's 28 but still he's my BROTHER not some elder I have to respect. He made me take down my Instagram video of me LIP SYNCING, Bodak Yellow by Cardi B. He said that I was "cursing" which I wasn't because I didn't even actually say the word. When he visits, he tells me to go to my room when I talk back to him and my mom yells at me for not listening to him, he sometimes takes my phone and keeps it until he leaves back home and he does more irritating stuff. This is so annoying and I do not think my brother should be having authority over me like he's my dad.
