Ah yes the "You have to do something to have a valid opinion on it." argument. We have dismissed that claim.
Patrons willingly support a Dev using the Patreon or similar Subscribestar model because they feel the group is doing something worthwhile (whatever that means to them): if they eventually don't feel that way, perhaps due to the Dev's actions or just a change of heart/circumstance, then it's up to them to decide if their patronage is warranted.
Anyone can feel taken advantage of if they choose, but in ICSTOR's case there's plenty of people who apparently still perceive the situation differently than you. That includes ICSTOR, and all of his project management methods you've claimed he could implement but won't out of some well-managed subterfuge. That is, he's managing *something* really well: fooling all his Patrons! That would actually take some work, oddly enough.
In the end, you'll just need to deal with the reality that not everyone sees things that way and for good reasons to them (including belief in what ICSTOR does offer his patrons, from status updates to previews, etc.)
