Earlier quoted context omitted.
I agree that there are a lot of other things to learn but accessibility is a legal and moral imperative, not just a nice to have feature. I think “lazy” might not be the right word since many developers don’t even know that they’re cutting corners, so perhaps it’s better to use “negligence” and realize that our field culturally encourages it rather than just blaming individuals.
In the end, software accessibility represents an edge case affecting a tiny fraction of users. You can argue it’s morally wrong to not support that edge case, but I do understand why it wouldn’t be a priority for most without legal prodding.
I'm curious: What fraction do you think it is? And what fraction do you think it should be for it to be taken more seriously?
