You are more right than you can imagine. The amount of "high and mighty complaining" I've seen on this very website is fucking absurd, especially the amount of "demanding" people who don't drop a penny throw around like they have any right to get pissy with the creators.
Although, even supporting doesn't give you the right to act like a dick to a creator. They're still human being. You can be mad at something without acting like an asshole, especially if you support a Patreon. You don't like it anymore ? Juste stop paying. Simple as that. That's a mature reaction. Not starting some sort of cancel crusade on some obscure forums...
Just look back on this thread at how many people treat Mulan like shit despite their efforts on the game, for example.
