The exact text of the first response above, by Lenord, is a copyright violation. I would quote it to be absolutely clear what I'm referring to but that in itself would perpetuate the copyright violation. Those exact words appear on this page,

https://www.defectivebydesign.org/what_is_drm_digital_restrictions_management

at the bottom of which is a copyright notice by the Free Software Foundation. Sorry, no offense intended, but the text jumped out at me because the FSF is the only place I've ever seen claim the R stands for Restriction. It normally stands for Rights.

Renderosity forum reply notifications are wonky. If I read a follow-up in a thread, but I don't myself reply, then notifications no longer happen AT ALL on that thread. So if I seem to be ignoring a question, that's why. (Updated September 23, 2019)
