No, it means that I'll soon stop supporting (for FREE) a group of (FREE) Extensions for those Community Rulesets that are not available via the FG Updater, which means that if a Dev of a Community Ruleset wants the users of their Ruleset to have access to the functionality of the DOEs they can base their Community Ruleset off of this Ruleset instead of "everyone" asking me to do all the work and make the DOEs work with their creation, and then me having to do all the support when something changes. It's shifting some of the the work from my single shoulders to the shared, collective shoulders of the Community Devs who would like the users of their Ruleset to have access to this functionality (and more).
As I said, the "'Standard' FG Rulesets (ie those available via the FG Updater) will not be affected." This means CoreRPG, 3E, 4E, 5E, 13th Age, CoC, CoC7, CnC, SW, Fate, d20 Modern, & PF (I think that's all of them).
Of course, some people may not think this is fair, in which case I just might throw a wobbly and withdraw all the DOEs, this Ruleset and everything else I've ever done for this Community FOR FREE (while still retaining my copyright to ALL of it), because the level of "entitlement" that has been growing over the last couple of months around here is starting to get on my nerves! (Yes, I'll take my bat and ball and go home!)
On the other hand, it's late and I'm tired (not to mention somewhat ill) so I might just be a little bit more tetchy than normal - I think it might be time for bed.
