Punishing groups for failing to implement accessability seems drastic, isn't there some to spurn them to action with incentivization instead? You catch more flies with honey..
If a shopping mall refused to build a wheelchair ramp, would you be fine with them not receiving any kind of penalty?
I think it's better to make these decisions in measured ways, rather than broad sweeping generalities, a shopping mall should have multiple motivations to build a wheelchair ramp before 'penalties' are used. I'm not inherently against enforcing accessibility, but it sucks to go for punishments as a first course of action.
Sometimes you just have to remind people what it means to be a part of a civilized culture with a properly sized stick. Special circumstances.
The honey is that being accessible could increase your possible market up to 10%.
If that's true then the punishments aren't really needed?
