I will share my opinion. I personally think if you pay money every month (even if it's small money, and if it's big, even more so) you must receive content once a month, well, two or three at most (even if there is very little content, a mini scene or something else).
A person should know that his money does not go into the void. This is especially true for the creators of visual novels, who can update for 6-9 months by charging subscribers, and at the output we get 5 minutes of content. When you take money from people, you essentially become responsible to them. If you just do a project in your free time without taking money for it, then no one has the right to demand anything from you.
But if you are on the content of your subscribers, be kind enough to provide them with content, people pay you money for work, not just charity, with such success you can just give money to a homeless person on the street, you will even do a good deed and clear your karma. Because of people like "Braindrop, Kompas Productions, Moochie, etc. who just pull money out of people", I stopped subscribing to the creators of visual novels, I buy on Steam (if the game is there) and that's it (like with Lust Academy, Being a DIK, etc.)
I'm tired of waiting for several years for the person to whom I give 10-15 dollars to provide me with a new portion of content and deign to take a look and release something. Or if it releases content, I subscribe for a month and do not renew. If I wanted to make money from visual novels, I would put all my efforts into it so that it would not just be my hobby.
To get a lot of money, you need to work and work tirelessly, developing an audience, skills and reputation, as in your business. I do not pretend to be truthful, and I am sure many will quarrel with me, but I decided to speak out on a topic on which I have already burned myself.
