Why I don't trust WCAG 2.2 and what I'm hoping from 3.0 - LogRocket Blog

Accessibility is a fundamental right and a legal requirement in many jurisdictions. The Web Content Accessibility Guidelines (WCAG) set the standard for digital accessibility, where non-compliance can lead to significant financial penalties. Inaccessible websites and apps cause considerable revenue loss, exemplified by the UK businesses losing approximately £206 billion annually. Additionally, the introduction of WCAG 2.2 has highlighted serious flaws, particularly regarding its inadequate color contrast algorithm, which often misclassifies accessible designs and fails to accommodate diverse typography effectively.
