Looking at your post history tells me that you took another person’s open source software and trying selling it as pro version without credit. Why did you do that?
Do you have any ethical sense when building or selling software?
That was the wrong assumption, as we released a library that imitates to be a pro version from the contributors of open sourcem We sorted it out by unpublishing the library. That's nothing to do with their tech in backend. Feel free to make comparisons on the output quality.
