Trolleys, veils and prisoners: the case for accessibility from philosophical ethics

# data[].attributes.blurb.html
Those who want to make accessible websites, will likely spend some of their time convincing others. One good reason to make accessible websites is that doing so is the right thing. For centuries, doing the right thing has been a concern for the field of philosophical ethics. In this talk, some notable philosophical thought experiments are applied to the world of web accessibility. With some practical examples, this talk makes a refreshing case for web accessibility, which people can use to advocate for more inclusive websites.
