In order for these freedoms to be real, they must be permanent and irrevocable as long as you do nothing wrong; if the developer of the software has the power to revoke the license, or retroactively add restrictions to its terms, without your doing anything wrong to give cause, the software is not free. A free license may not require compliance with the license of a nonfree program.
It is acceptable for a free license to specify which jurisdiction's law applies, or where litigation must be done, or both. Most free software licenses are based on copyright, and there are limits on what kinds of requirements can be imposed through copyright.
If a copyright-based license respects freedom in the ways described above, it is unlikely to have some other sort of problem that we never anticipated though this does happen occasionally. However, some free software licenses are based on contracts, and contracts can impose a much larger range of possible restrictions.
That means there are many possible ways such a license could be unacceptably restrictive and nonfree. We can't possibly list all the ways that might happen. If a contract-based license restricts the user in an unusual way that copyright-based licenses cannot, and which isn't mentioned here as legitimate, we will have to think about it, and we will probably conclude it is nonfree.
Finally, note that criteria such as those stated in this free software definition require careful thought for their interpretation. To decide whether a specific software license qualifies as a free software license, we judge it based on these criteria to determine whether it fits their spirit as well as the precise words. If a license includes unconscionable restrictions, we reject it, even if we did not anticipate the issue in these criteria.
Sometimes a license requirement raises an issue that calls for extensive thought, including discussions with a lawyer, before we can decide if the requirement is acceptable. When we reach a conclusion about a new issue, we often update these criteria to make it easier to see why certain licenses do or don't qualify. It seems strange to make something available without payment and then get mad when people don't pay.

It's going to take some careful writing of licences to give developers more control over how software they open source is used in the ways they want, without stopping the open uses they want to enable. Righting Software, book review: Building blocks for software architects.
You may unsubscribe at any time. RubberDuck I don't see the misconception. At no point do I specifically say that you have to pay for libre software. I did my best to avoid stating any cost, but there is no reason libre software cannot be charged for as well However, Free as in Beer in the context of the saying does state that you have no access to the files and is provided for free So I feel like you're missing the point I think this quote answers the OP's question pretty well.
However, to make the meaning of "free software" crystal clear, the FSF goes on to list the "four essential freedoms" that characterizes free software: The freedom to run the program as you wish, for any purpose freedom 0. The freedom to study how the program works, and change it so it does your computing as you wish freedom 1.
Access to the source code is a precondition for this. The freedom to redistribute copies so you can help your neighbor freedom 2. The freedom to distribute copies of your modified versions to others freedom 3. By doing this you can give the whole community a chance to benefit from your changes.
