Objective of this paper is to explore the features of different regulatory cultures and systems through their interactions with mega-platforms. By developing a taxonomy around the regulatory and policy responses to the advent of mega-platforms, we are able to better understand both the mechanics and the nature of a regulatory culture . Our main argument is that the more polycentric or multi-modal a regulatory system is, the more likely it is to be able to provide an adequate response to the invasion of mega-platforms in its habitat.
