If you go to the plagiarized product page (http://www.chupamobile.com/products/details/600/Secured+Chat...) and click more info under Regular License, the license terms are more restrictive than the BSD, which is a violation. However, the author is in Indonesia, so there's probably not much recourse.

I think you are confused with the GPL.
BSD only requires you to acknowledge original authorship, and declines any suitability or liability. It requires you to preserve the first. (You're welcome to take liability, though ...)
Edit: the plagiarist is in Indonesia
