However, your claims that you'll have to keep paying in order to keep playing seem bullshit to me. DS might make some stupid decisions, but I doubt he'll do that. I guess we'll have to wait and see.
I mean when you look at how the game is delivered, it's not actually that crazy at all.
Consider you are a $20 patron. You pay that much to get access to the latest build of the game the second it comes out. You like the game and are happy with the content. You sign in with your Patreon account and all is good.
Now let's say next month you run into financial difficulties, and you have to pause or delete your pledge. You decide to log back in to play the old content you didn't get to... even if you'll have to wait for the new stuff. Well, suddenly you can't. With BB, if you stopped pledging you at least always had the last version you downloaded. Here, public releases might be up to two months or more behind the latest release, and they will have less content to boot.
Or another example, let's say you subscribed via his website to have access to the taboo subject matter. And again, you stop supporting him there, does all that content gets cut off? None of this is guaranteed to happen, but it does seem pretty likely considering how these accounts will have to work.
