8.7Accessibility Overlay Widgets: A Legal Trap

Many companies purchase "accessibility overlay" widgets (e.g., AccessiBe, UserWay) thinking they solve compliance. Courts and accessibility experts disagree:

• Overlays do not achieve WCAG conformance. They apply surface-level fixes (font resizing, contrast adjustments) without addressing underlying structural issues.
• Multiple lawsuits have been filed against companies using overlays. Courts have ruled that the presence of an overlay does not constitute a good-faith accessibility effort.
• The National Federation of the Blind has publicly opposed overlays, calling them "not only ineffective but harmful to accessibility."
• Overlays can interfere with actual assistive technology. Screen readers may conflict with overlay scripts, making the experience worse, not better.

The only reliable path to compliance is fixing the underlying code: semantic HTML, proper ARIA roles, keyboard accessibility, and sufficient color contrast.

Understanding the legal landscape transforms accessibility from a "nice thing to do" into a business-critical compliance requirement. Frame it that way, and budgets and priorities follow.
