Fact is simple. Usually, people wich choose to buy addon don't want to share it with other... :-/
Many addons updates here can be found on russia warez website, before an upload here.
Members which don't have access to a module and absolutely need it, could make a pot, then buy it, and share together and on the forum. :)
Be smart guys, it's better to buy a module 5$/€ than 100$/€... ;)
