While it is spiteful and petty for a developer to add filler text preventing Patreon from giving some bits for free, I do to an extent understand where they are coming from. It is their content and you're supposed to be paying for it. By giving it out for free, it means they make less money and have a harder time making their game.
However, I almost entirely disagree with the mindset as a whole.
This is the internet - the place where anything of even slight popularity will be pirated. The only way to prevent it is to either never release in the first place or to embrace it to such an extent that piracy is never necessary.
Cracking down on it isn't going to help. Instead, it only fosters animosity. Like Darth said, some may want to support but aren't capable of doing so for one reason or another. Being a prick to those people isn't going to make them happy and will only lead to an angry community.
Oh, woe is me, then! Should I stop making my game because you won't support me? :: If that is what you want, I can't stop you. Just know that it shows what you really are. Maybe you were a passionate developer once, making your game because you wanted to, not because it was an obligation. Maybe at some point it changed or maybe you never were truly passionate. Like I said, I can't stop you. If you quit, I highly doubt this message is going to be the tipping point that makes you do so (and I truly wish it isn't). Just know that its a stain on your reputation and something that you are likely to repeat again with every large project you do.
What I'm saying is that being petty about piracy isn't healthy. Its not healthy for you and its not healthy for your community. You may think you're protecting your way of living by doing so, but you aren't. You made a marvelous game with ratings so overwhelmingly positive that its on the second page for top rated games across the entire site. These people in this thread are a part of your community and those with your game plastered under each of their messages further spreads it across the site. You should be proud of what you created. Can there be bad apples in the community? Of course. There can and are those. You are fully within your right to ignore them. You are also fully within your right to ignore this entire section of your community. However, seeing this petty behavior of actively going out of your way to exclude this part of your community makes me weary of supporting you and I'm certain I'm not alone in that.
Take a look at the two icons below my name. They are both fantastic developers who I chose to support. To me, the incentive to support them was not because I'll get an update early and not so that I can speak with the developer. It was because of their behavior towards the community that I did so. One of them not only releases their game entirely for free with no delay to those not supporting them, but also freely releases some of their assets for others to use. The other made a fabulous game with another in early stages and only a one-week delay between patron-release and public.
I'm sure there are others like me. We may love your game, but seeing you acting hostile towards people that support your game makes us, or at least I for one, weary. It makes me worry that you'll blow your lid, delete all the game files, and go dark. Maybe, rather, you'll decide to suddenly drop development on Intertwined and move to a separate game. This, to me, isn't the behavior of a passionate developer. This to me looks like the behavior of a vindictive IP lawyer who doesn't care if you like their game. Its something they don't like and must take extra effort to prevent.
I truly wish you the best with the game Nyx, if you're listening. Just know that your behavior is leaving us weary and annoyed.
Entitled whiners who think they know better than the Dev's are a growing problem around here.
