I have no specific opinions on the author really, but:
> Seems like an author that doesn't understand the spirit of FOSS.
The author states he understands the licensing and the project's rights to use his software earlier in the thread. He was simply making a request.
> Why is a person like this even engaged in FOSS if they don't have a desire to share or even engage in a reasoned discussion?
Again, he stated his reasons in the thread. He didn't want to have to potentially support their repackaged and/or old versions of his software.
His software being OSS did not give up his right to make nuanced requests.That said, the thread ended with something to the effect of "well, we can include instructions on how to install his software" -- an option which wasn't presented until the end, yet it fully complies with his request.
