As someone already said, artists should make all the works for free after some time. And in high resolution too. Not some cropped or resized images.
And Patrons could get bonuses like .psd files or something. And we wouldn't need sites like this to get it.
Paywalls are dick moves. They already earn way more money from anything. They got YCH, they got commissions. And they get real money from it. Definitely more than I'm getting from real job. If the paywall was broken, they still would get so much money. One commission that gives them almost my month's worth salary for example. And they got more than one commission in a month. Plus still Patreon would get their the moneys. People would still want to support honest creators. And maybe even I would pay, then. Because I'm against paywalls, so I won't give any money for such people. And with no paywalls, I would just support people who are fair with me. Still bonuses for Patreons would exist. Earlier content. .psd files. WIPs. And in terms of game content, early build, test build etc. Your influence in the projects or artwork. It's still great perks people would want to pay for.
If they did that, everyone would be happy. And no piracy would exist. I know some people that were actually "forced" by fans to register Patreon account. Because they didn't want to get the money from them. But the fans wanted to give the money themselves. That's what You call loyalty. And loyal fan is better than forced fan. Why can't more people understand that. And there is definitely one furry artist I would never give a single cent to. Some people may know who am I talking about. But I won't say the name or answer if You ask for it.
If the Petreon (etc) artists won't change that, piracy will find a way. Like a phoenix it will rise from the ashes. If not yiff.party, it will be something else. More or less friendly for users. But it will not end. Piracy exists for far longer than Patreon. And it will go beyond the life of this website too.
