I was going to ask "why?" before I read in the overview the reason being helping non Arabic speaking learners of the language. It still defeats the purpose of learning a language to be able to read literature written in original script and communicate in writing with the language readers. The only case where I see this useful is when verbally communicating using words memorized using this Latin script as tourists do when visiting a foreign land.

As an Arab I also hope that the motivation behind this is not ideological. Like how the Turkish language was transformed to use a Latin-based script system.

Edit: As of the claim of it being useful to Arabs, please no! Arabs when use "Arabish" tend to use it badly with no vowels making pronouncing words hard and sometimes ambiguous. The "Arabish" trend was popular in the 90's (in the infancy of Internet or at least Internet penetration) and has declined dramatically in the 2000's. Arabs lazy enough to not write in Arabic script would also be lazy enough to not learn the proper usage of this Latin script.
