List of technology design decisions that marginalize people

This is a list of technologies which in some way (perhaps unintentionally) marginalize some users based on gender, race, class, sexual orientation, disability, etc. It provides motivation for having a diverse group of people participate in creating technologies. 

General issues

• Much software has problems with accessibility, making it unusable for people with visual impairment or other disabilities.
• A large amount of software is only available in English, and translated software often into only a few other languages.
• Some software restricts text entry to, eg, the Latin character set.
• Some software relies on artefacts of the Latin character set for key features (eg, relying on spaces between words; not all written languages segment words with a special character at all)
• Much software is only available for comparitively recent (and thus expensive) hardware and/or platforms.
• Use of most software assumes at least a moderate standard of literacy.
• Developing software is even more likely to require knowledge of English or at least command of the Latin character set.
• Software that uses icons instead of words may still often assume a great deal of cultural literacy, usually with Western European-North American cultures and their symbolism. In any event, unless verbal equivalents are given, such designs are inaccessible.
• Much software makes very restrictive assumptions about people's names, some common examples being that everyone has exactly two "important" parts to their name, that everyone's name is written in Latin characters, or that names do not contain "special characters" like hyphens. See for example Who is harmed by a "Real Names" policy? and  Falsehoods Programmers Believe About Names.
• Much software relies on United States-specific addressing information, such as requiring ZIP codes and selection of a US state of residence. (Even "postal code" which is sometimes used as a substitute, isn't universal. See Falsehoods programmers believe about addresses) Websites that only accept US credit cards or only ship to US addresses often do not make this plain before the customer has invested considerable energy in assembling a purchase.
• Many computer keyboards are designed for people with larger hands, putting people with smaller hands (who are more likely to be women than men) at higher risk for repetitive strain injuries. Likewise, office chairs and desks are often designed for taller people.

Specific examples

• The HP MediaSmart webcam fails to track darker-skinned faces . HP says that It's "built on standard algorithms that measure the difference in intensity of contrast between the eyes and the upper cheek and nose." 
• One of the X11 , HTML , and CSS color names is "Indian Red". 
• The options for "relative" in the iOS address book do not include "cousin". This marginalizes cultures in which extended families retain close ties. 
• A large portion of website registration forms ask for the user's gender but only provide options "female" and "male".
  •  Some forms provide the third option "other", which many genderqueer people find just as marginalizing.
• git doesn't allow retroactive name changes.
• Facebook, and perhaps other social networking sites, don't allow users who are in open relationships to list themselves as "in a relationship" with more than one person.
• Computer games with romance/sex plotlines or mechanics often have restrictions on relationships:
  • no, or fewer, options for same-gender relationships
  • not allowing consensual or publicly known relationships with more than one partner
