Is your product accessible?

To give context, I worked on a lot of digital transformation within GOV orgs here in Canada, and a few years ago it became mandatory for all digital touch-points to comply with the AA Accessibility standards set by The World Wide Web Consortium (W3C) Today, anyone, regardless of their background, can launch a product or service, so I'm genuinely curious to learn how many of PH community a) even know what Accessibility is, and b) Consider it when building their product?
