FWIW, they do. There's constant efforts to ensure apps are accessible if you use a screen reader and to not exclusively rely on sound for notifications. Additionally there's care to not assume people are using keyboards and mice when interacting with something ("tap" vs "click" vs "select" vs "pick", etc.). At least with the teams I've worked with there's a considerable amount of effort done in these areas.
