I would have given this extension a better rating if it supported PDF’S and if the author actually understood the GPLv2.0 licence.
If you have PDF enabled for the document any user logged in or not can see the hidden content within a PDF. This is a major bug as far as I am concerned.
My other problem is with the distribution of this GPLv2.0 licensed product. While I don’t mind paying for it, I do mind being presented with a statement on the authors download page that tells me the extension is for my own personal use and I cannot distribute it. This is a clear breach of the GPLv2.0 licence. Obviously the author cannot change the licence for the current version which as it stands allows anyone to modify and distribute the extension. However If the author wishes to protect future versions of this extension I would suggest they take look at an alternative licence.
Owner's reply:
Hi Kyle,
What you have reported as a bug could better be termed as a feature request :)
My aim was to protect the text content from the non-registered users and so I have created a plugin following my requirements. And it does that well..
I'll surely look into enabling the pdf security, if time permits.
Regarding the license, - you "cannot" distribute it.
Please contact me via forum/email if you have questions about the license.
