Every company is looking for that one-size-fits-all solution to accessibility that will cost them next to nothing, solve all of their problems, get a gold star for being compliant, and keep the lawsuits at bay. Thus we've seen more and more "overlay" solutions make their way into the world and they have faced harsh criticism from accessibility practitioners to the point of complete rejection of the concept.
