Let’s say you write Book. You must focus and concentrate to finish it. Then its done. Yes, you just release you idea and knowledge.

Can i say it same as you write Software and compare the content in the book is same as software content.

But customer want buy for the content inside book. Cannot read it before buy.

Software same also. You cannot use it before buy.

They all same as free chapter sample and try-it software.

Free software is different. They not involve in business profit. You can profit from their services. You win and get extra profit.

But Commercial software is not the same. They give you support and maintenance. But your work must have salary. Like i will do it for specific work and they pay me.

In open source is different. Because open source is project evolution to non-profit organization.

People still buy Book and they still buy software because all is important in our life.

Open source project can attract so many developer. Because they business with developer. If they increase developer number.
They will make money.

Conclusion: Software is same as your business but not free download imagination.

Better you buy it before it close to public. No left offer.

Open source is just make developer access to specific target. Not product. But services.

You have software and customer need to buy it. They must have different license type.

Free license type is give only for non commercialize software. This free license can give reputation to the author and developer.

Better think about your license and give them shareware for trial use or demo. This type of license just for promotion.
