I admit this is pure speculation. There are mentions in another article[1] that some restaurant associations supported it:

>The measure has the support of Gwyneth Borden, executive director of the Golden Gate Restaurant Association and other local merchants.

It seems suspicious that before the legislation is even introduced exceptions have been carved out for the existing big companies.
