My assumption isn't that he is "Just a scammer", I think he is a procrastinator (which to my recollection he hasn't stated for himself), that over-promises and under delivers. When his feet start being held to the fire, he drops a bunch of "personal drama" to try and cover his ass... And if I am right and he loses subs for solid honest communication, that's better for everyone (except maybe him, but his supporters are pretty fanatical.... most would likely stick around).
If he wanted to do 1 update a year, or every 6 months, Everyone would be fine with it, I agree with you on that. Problem is he doesn't convey what his plans are, and as soon as he does, he shoots himself in the foot and breaks his word. If he was honest, and communicated clearly, he wouldn't have most of his issues.
