There was so much uncertainty around it and who wanted what that a lot of people voted against their best interests. I'm still meeting people who thought they were voting against Uber and Lyft with that proposition.
The ads were constant and incredibly misleading. And that was one issue. Every time these propositions come up, I can usually find 3 or 4 that are not what they seem (the Diveta props are similar but very different tactics afaict).
If all state business was done this way it would be overwhelming to filter through it all.
