Semitic languages are easy to write without vowels because the meaning is very obvious even if you omit the vowels, but in many languages you have a great deal of collisions if you omit vowels.
It's the same reason Chinese characters are a poor fit for Korean and Japanese. Chinese is not an inflected language so one symbol for a word works quite nicely, but other languages need a way to add prefixes and suffixes to works.
Also, middle persian had a native abjad [1]. (As well as a derived alphabet [2])

If almost all literate people know the latin script, there's a benefit to writing your language in it. Of course, the switching cost is high.
The results are likely much better than random texts using cyrillic, greek, arabic, hangul, etc.
Otoh, If they're typists, I expect they can likely type them into a search, probably sans diacritics, but that's likely good enough for searching or looking through a translation dictionary.
Greek and Cyrillic may share enough symbols that a latin script user can make due with an onscreen keyboard or a dictionary with great effort. But a completely different script would need even more effort.
