Snapchat does not play nice with its most popular users because it prioritizes user privacy and wants to avoid giving celebrity users an unfair advantage over others. Snapchat believes that its users should all have an equal experience on the platform, and it does not want to create an environment where celebrities are more likely to receive attention and engagement. Additionally, Snapchat does not want to give celebrities too much control over their own accounts, as it could lead to them using their influence to manipulate the platform. By treating all users equally, Snapchat is able to maintain a more level playing field for everyone.
