Okay so you didn't give them out. Which strengthens my resolve for this debate even further. You have been wronged by the entitled community.
http://forum.blockland.us/index.php?topic=241926.0Here's a great example of when Private add-ons should be frowned upon.
Port made soft shadows. Originally not planning to release them (Not publically stated)
She made a thread showing them off to people.
People complained, for good reason. The thread's purpose was to rub it into people's faces.
Finally Port released them.
Should Port be forced to release them? No.
But rubbing them into people's faces isn't cool either.
Btw like 90% of blockland players don't even have good enough computers to run shaders above OFF anyways.
But besides my point.
