I dunno. I agree this work is important, but I also find it boring and frustrating. Its like adding logging, plumbing configs, etc. Obviously it has to happen, but at least for me it's neither interesting nor exciting.
Making sure that people aren't blocked from completing a task due to a situation beyond their control, such as a physical disability, seems pretty important to me. It's true that some organizations only implement accessibility for the sake of preventing lawsuits, but there's a legitimate reason to have that legislation in the first place.
