A recurring discussion I have with people is whether something that is free-libre can actually be as good (if not better) than a shrink-wrapped product that is sold.

I elaborated about that in the ABOUT section. The word "free" in free-libre open-source refers to freedom and not necessarily cost. The fact that the software is free in the Software Freedom sense opens the door to it being used in a commercial setting without the overhead involved with proprietary licensing costs. It also allows the software to be improved by anyone with the ability to look at the code and improve it.

So, the Ubuntu-Rescue-Remix can do just about anything the proprietary equivalents can do, except the Rescue-Remix will get even better with time for free.

The business model of free and open source software is services and support, not sales of a software product. That means no one will sell Ubuntu-Rescue-Remix in a shrink-wrapped box in a store.

It doesn't mean you aren't allowed to use it commercially, though. I encourage you to use it in any setting, including in a commercial environment.

Anyone is entitled to obtain it, use it and charge customers a fee for the service of recovering their lost data if they chose to do so.
