Piracy is a double edged sword. It can both hurt you and help you. Regardless of what the industry been hampering on forever, a pirated work is not the same as a lost sale, because the likelihood of those that pirate would actually buy up front to start with is less. But someone that pirate might get to like something they otherwise wouldn't. And then turn into a customer/supporter. But then of course there is those that never would buy/support regardless and just happy about get it for "free" whether they like it or not.
For indie devs such as this one, their business model if limited to patreon is a rather vulnerable one. You have patreons that support because they like her work, and those that support to gain access to it. Those eager top supporters that all in for early access to alphas etc, when they see other people get for free what they pay for, maybe they start re-consider the level they pledge at. I don't really think its fair to lash out at the creator for being a bitch, greedy etc for wanting to protect her business. Who knows, maybe she went full in and this is her livelihood. I don't think anyone else here wouldn't want to protect their income and paycheck as well.
If you really like something, support it, don't lash out for not get your next freebie when you want it.
