The greatest tool for us as accessibility professionals is diplomacy, the quiet art of stating your case and pushing just enough to encourage change.
All online services must be accessible, but this is undermined when we secure the service with CAPTCHA. A technique of layered security can be a suitable alternative which protects the integrity of your website and maintains the accessibility.
We need to think about accessibility as not only ensuring web content is accessible but making sure that a culture of accessibility permeates through an entire organisation.
The effort making your products accessible will benefit you. It will put you at an advantage in the government procurement process and reduce your risk of legal action.
