For me, RP2's problem isn't quite elitism. It's that other people treat her like a divine, graceful goddess. People in the forums constantly say that RP2 is the best mod out there and that it's a central part of FTB.
If I was hypothetically going to worship Eloraam for anything, it would be intelligence and technical skill. To me, the content of the mod itself is indicative of genuine brilliance. It would not, however, necessarily be for generosity or social grace. She released the mod under a closed source license. Said mod uses a proprietary power system that isn't compatible with anything else other than via the blulectric engine, and as far as I know, no API exists.
This mess (as does Minecraft itself, in vanilla terms) also offers a fantastic example of the inherent superiority of open source as a paradigm, as opposed to keeping something closed/proprietary. It's a fairly simple fact that anything which is kept closed, is not going to be developed or maintained as rapidly or effectively as software which is open source. The lion's share of content for Minecraft itself comes from the mod community, not Mojang, and it always has; in reality, Minecraft alone could really be considered more a development platform than an actual game, when you consider how limited vanilla is by comparison.
So it is with RP2. The codebase has apparently grown larger than a single individual can handle. If it had been made open source, Eloraam would have had help, and the mod would have kept up; she even would have been able to pass it on when she hit burnout, as SpaceToad was able to, due to BC being open source. Again, people can point out that making something closed source is a developer's right; and I'm not arguing with that. What I'm saying is that while it might be the developer's right, it's also dumb.
It is true, however, that I also consider RP2 indispensable, and that is a very large part of the reason why I care enough to write threads like this. People should realise that anger or unhappiness about something is actually indicative of emotional investment. It doesn't make any sense to get upset about something that you don't care about; you're obviously not going to do that.
That does not, however, for one moment mean that I remotely condone anything vaguely resembling what someone else here said about Eloraam receiving death threats; and I want to make that totally and completely clear. I would never wish harm to her in personal terms at all; I am expressing frustration, yes, but becoming genuinely vindictive is not my intent.
