Big businesses will just find ways to circumvent it like starting meeting with a copyrighted poem and arguing that minutes can’t be shared on copyright grounds (or similarly absurd loopholes) which smaller businesses wouldn’t think of doing. Thus big businesses end up getting a greater competitive edge.

Basically whatever process you put in place to level the playing field, big businesses will find a way to game it to their advantage because they have the resources to do so and the deep pockets that allow them to take risks.
