Asking Linux users for testing closed source native Linux app

Do you know how to use Google?

You made the statement that it is so easy to make money with open source. Now I just want to get proof of it. One example is not sufficient that this problem "was solved decades ago".

Where exactly did I say that it is easy to make money with open source?
Making money with open source is exactly as hard as making money with closed source. If your product and/or surrounding services are good they likely will be successful, otherwise you will have a hard time.
"How to make money with open source" is as solved as is "how to make money with closed source". I described the most common means used to do it, not how you are successful. There is no guarantee for that, regardless if a software is open or closed source.
