Final answer:
Instructions need to be accessible to accommodate individuals with disabilities, ensure equal access to information, and to improve user experience, but not to limit access to people. Enhancing accessibility is intended to remove barriers, including for those with disabilities, and should not serve to restrict information access to fewer people.
Step-by-step explanation:
Instructions need to be accessible for a variety of reasons, but not to limit the number of people who can access the instructions. The reasons for making instructions accessible include accommodating individuals with disabilities, ensuring equal access to information for all, and improving the user experience. For example, following the American with Disabilities Act (ADA) guidelines and the Web Content Accessibility Guidelines (WCAG), texts and learning materials are created to be accessible through features like informative titles, improved color contrast in illustrations, and comprehensive alternative text to assist those with visual impairments.
However, limiting access goes against the very essence of accessibility efforts, which aim to include as many people as possible by removing barriers to information, whether due to disabilities or any other factors. Accessibility enhancements serve to broaden individuals' ability to receive and comprehend instructions, not to restrict it.
