The digitalisation of the public sphere is an ongoing process accelerated by the ubiquitousness of the internet. For the over a billion people estimated to live with an impairment, this digitalisation comes with barriers that can represent an altogether exclusion from the digital realm, hindering their full participation in society. This context should compel stakeholders involved in the development of digital products to consider accessibility as an essential requirement. However, that may not always be the case. This work is the product of a scoping literature review guided by the overarching topic of accessibility in the context of the web. After arguing that disability as a phenomenon might be more prevalent than one would think, it frames web accessibility as a human right that benefits all individuals, while also having important dimensions that businesses would regret ignoring.
