Accessibility is a second-class citizen for a lot of clients, therefore a lot of web agencies. In my two years working in one, only once was I tasked with a fully accessibility compliant site, and that was because it was government subsidized. Clients will gladly pay to move buttons and complain about a particular shade of blue or opacity transition speed, but god forbid we deliberately put any hours towards making the site accessible. We could try all we want to talk them in, they were the ones who paid in the end, and most of them just don't give a crap.
Most of our devs were pretty thorough about doing the most they could in the given time frames anyway, but it pretty much never was made a priority.
