Something that strikes me as odd is that some are basically complaining that people are doing things they don't like with the first party's own money. I know, it happens all the time, and I internally mock people who waste money on trashy romance novels (amongst other things), but...really? Did it ever occur to ya that maybe the folks who are giving her Patreon donations are folks that would've done so in the beginning had that been an option? Shit, if I had my own discretionary cash (I earn somewhere on the low end of "jack shit" currently), I'd happily throw a dollar or two a month her way. Elo helped create Forge. Forge has worked as a framework for pretty much every mod that we enjoy nowadays. She created the Ore Dictionary, which is why having 17,000 different copper ores isn't a problem, anymore.
Elo contributed to the very core of modern Minecraft modding. Has she been active in the past year or so? No, but life happens, and Elo's a very private person. However, she also seems very sensible. If she didn't want to work on RedPower again, I'd be willing to be that she'd just come out and say it. It'd save a lot of time, bullshit, and drama. All in all, I say live and let live. Eloraam is back, and that's bloody awesome! We've got one of our oldest hands back in the action, and I have no doubts that whatever she makes will be every bit as awesome as the original RedPower was way back when.
