Can’t access the article but IMO websites with low accessibility often have major usability issues, e.g. can use without a mouse, non-focusable buttons, wrong form elements, validation errors with pop-ups, forms get stuck in weird states, scrolling has annoying side-effects, etc.
If that is the case I wouldn’t be surprised if churn rate was negatively correlated with accessibility.
