Power structures! At least in my country, most (good) developers are more comfortable in English, because English is the way to economic success (thanks colonialism). These people are not really interested in doing the hard work necessary to fix the many RTL bugs present in various programs. For my language, Urdu, the web is far more broken than for Arabic. RTL fonts used on most major websites are adequate for Arabic, but not for Urdu, because the Urdu script contains additonal characters that Arabic script does not have. Moreover, Arabic fonts are in the Naksh calligraphic style, while Urdu speakers are more comfortable with the Nastaliq calligraphic style. I personally use Greasemonkey to force Nastaliq fonts for RTL content on various major websites.
