If a blind person, or any person with accessibility needs, tells you what they need, listen to them. It is absolutely rude in the worst way to either push things on them that they don't want, or restrict them from things they do need. Denying someone accessibility, or forcing measures on them, is so, so rude. If you haven't experienced the situation the person is in that makes them require accessibility, you have no idea what they're going through. Listen to disabled people. Listen to their needs. Give them what *They* request, not whatever you think is best.
