I find it strange how, in an industry where people will eke out minor percentage improvements on conversation rates, "we" are so happy to just intentionally slice off a portion of the potential user base to never be able to use the software.
But because conversion rates are typically low and because of how the math works out for a funnel product, there's a larger business impact depending on which 2.3% is cut out. (Ignoring the negative business impact of being non inclusive/a11y)
12% vs. 10% is a 20% decrease in performance.
100% vs. 98% is a 2% decrease in performance.
I'm not arguing against a11y. I'm just saying, that's why ADA exists. It's not in the business interest without the law. Also it's just good ethics to be accessible.
I'm not sure exactly what this 2.3% is (for "blindness"?), but significantly more than 2.3% of the population wear perscription glasses. Those people have visual impairment and use assistive technologies
Screen readers are not the only assistive technology. Especially on phones, many people use assistive tech to increase font weight or size. Ignoring these options will remove customers.
