Dark Silver didn't abandon the game due to Patreon, but rather due to having lost interest in the game. DS started out well enough, but quickly began to try and please everybody, listening to his fans idea of how his game should be. He clearly had big plans for Eric, but felt forced to remove him due to pressure from his fans. With every update, you could feel his fading interest, both in his responses to his fans, as well as the game itself.
When Patreon changed their policies, every big game handled it just fine. Dreams of Desire, Dating my Daughter, Man of the House, and many more, all found solutions to the patreon problems and their games are still alive and well. Dark Silver could have easily adjusted his game like the others, but BB had evolved into something he never intended and he was pretty clearly lacking passion for the new adaptation.
He took the first and best excuse he could find and abandoned ship. Now he is working on his new game, which he is clearly way more passionate about, although his former fanbase are revolting against it to no end.
Just goes to show that listening to feedback is okay, as long as you stay true to your original vision.
