Would You Buy A Program from This Developer?

In my continuing shock at the sheer masses of uneducated at all positions in society, I've come across a bit of a shock at "mozdev.org - autocopy: index". The developer of this program - really just an additional component for Seamonkey and its narcissist cousin Firefox - describes his little product and shows a command of the English language we'd expect of a child of nine.

Either the developer really is nine years old, has absolutely no command of the English language to speak of, is too inattentive to detail or simply too stupid to write English.

And I sure as hell am not 'buying' (for even free software isn't free) something as complicated as a Seamonkey extension from people who cannot even find the 'spell check' button on their browser. Writing a description of your product in all but broken English is not a way to inspire confidence!
