Is it wrong and controlling to ask my partner not to post things on social media?

My husband is someone that's really obsessed with social media. He will post anything even about our relationship difficulties and problems. He likes to share them online so that everyone will see. The idea that everyone could see that makes me feel uncomfortable. Oftentimes, he tried to put other people down and criticize them on his Instagram story.

Meanwhile, I'm someone that's really private and don't like to share things on social media, especially about my personal life. I asked my husband not to share anything about our personal life on social media. I asked him to be more private. He cries and gets mad at me for asking such a thing.

Is it wrong of me to do that? Am i being too controlling of my partner's behavior? How to deal with a partner that likes to expose our personal life on social media such as Instagram?
