Okay I can't go against that because it's true for the first part
But if small Devs don't use it what will stop people to steal their works? To have faith in people?
People will try to hack it and that's normal but less people will do that if there's some protection
Here is reality as a software developer of any size.
Either do what you do, realize some people will use your work without paying for it.
Or spend a bunch of time trying to prevent people from stealing your work, then watch in horror as they do it anyway and the net impact of your efforts is that you wasted time on it and made the experience worse for your paying users.
Is that great? No, but that's reality. It has been for at least 30 years. That's speaking as a software developer. When it comes right down to it, most of the people who steal your work were never going to pay for it anyway. What's worse is that often you will get customers when someone steals it, then tells a friend who pays for it. Speaking specifically to F95, I have yet to become a patron for any project that I just randomly found on the internet. On the other hand I've been a patron of several that I've found here and liked.
So how do you get people to pay rather than steal? Stand out. Offer the best quality content. Few people are going to become a patron for a mediocre or low end product, but many will for a really great product. I'll say that CA 1 was quite good, I supported it.
