Patreon is rad and people going to it shouldn't be the issue here. It's basically a way of directly supporting regular output where it would be posted online or freelance (webcomics, article writing, videos) or funding content which might cost too much time or money out of someone's pocket otherwise. Patreon money is usually used to either support someone's living to make ends meet or pay for stuff like airfare, materials, or extra help.
I can't speak to this and I kinda don't want to as I've long avoided Jim Sterling. Good for him for striking out on his own and further filling out where making a living doing this thing can go.
