Apart from these two organizations, the Debian project is seen by some to provide useful advice on whether particular licenses comply with their Debian Free Software Guidelines. Debian doesn't publish a list of approved licenses, so its judgments have to be tracked by checking what software they have allowed into their software archives. That is summarized at the Debian web site.
It is also possible to purchase products in small "trial size" containers. This is common with toiletries such as shampoo, which are useful for vacations or other travel, where large bottles or other containers would be impractical (or more recently, not permitted for air travel). These are also often provided in hotel and motel rooms for the guests. Samples may also be loaned to the customer if they are too valuable to be given for free, such as samples of a countertop or of carpet to be used for remodeling. Sometimes companies in b2b market will offer sample of data or service for free before engaging business relationship.
In 2006, OpenBSD started the first campaign against the use of binary blobs in kernels. Blobs are usually freely distributable device drivers for hardware from vendors that do not reveal driver source code to users or developers. This restricts the users' freedom effectively to modify the software and distribute modified versions. Also, since the blobs are undocumented and may have bugs, they pose a security risk to any operating system whose kernel includes them. The proclaimed aim of the campaign against blobs is to collect hardware documentation that allows developers to write free software drivers for that hardware, ultimately enabling all free operating systems to become or remain blob-free.
One of the most popular synchronization services ever: simply put files in your Dropbox folder on the desktop, they get uploaded to the cloud, and are instantly synchronized with any other PC on the account. Files are also accessible via apps or the Web. If you delete a file by accident, you can use the site to get it back. You get 2GB of free online storage, which you can bolster by sharing on social media and downloading the mobile apps.
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.
Free software played a significant part in the development of the Internet, the World Wide Web and the infrastructure of dot-com companies. Free software allows users to cooperate in enhancing and refining the programs they use; free software is a pure public good rather than a private good. Companies that contribute to free software increase commercial innovation.

"In contrast to commercial software is a large and growing body of free software that exists in the public domain. Public-domain software is written by microcomputer hobbyists (also known as "hackers") many of whom are professional programmers in their work life. [...] Since everybody has access to source code, many routines have not only been used but dramatically improved by other programmers."
