This last point, which allows the software to be sold for money seems to go against the whole idea of free software. It is actually one of its strengths. Since the license allows free redistribution, once one person gets a copy they can distribute it themselves. They can even try to sell it. In practice, it costs essentially no money to make electronic copies of software. Supply and demand will keep the cost down. If it is convenient for a large piece of software or an aggregate of software to be distributed by some media, such as CD, the vendor is free to charge what they like. If the profit margin is too high, however, new vendors will enter the market and competition will drive the price down. As a result, you can buy a Debian release on several CDs for just a few USD.
Many people write their own license. This is frowned upon as writing a license that does what you want involves subtle issues. Too often the wording used is either ambiguous or people create conditions that conflict with each other. Writing a license that would hold up in court is even harder. Luckily, there are a number of licenses already written that probably do what you want.
Freedom 1 includes the freedom to use your changed version in place of the original. If the program is delivered in a product designed to run someone else's modified versions but refuse to run yours — a practice known as “tivoization” or “lockdown”, or (in its practitioners' perverse terminology) as “secure boot” — freedom 1 becomes an empty pretense rather than a practical reality. These binaries are not free software even if the source code they are compiled from is free.
The freedom to run the program means the freedom for any kind of person or organization to use it on any kind of computer system, for any kind of overall job and purpose, without being required to communicate about it with the developer or any other specific entity. In this freedom, it is the user's purpose that matters, not the developer's purpose; you as a user are free to run the program for your purposes, and if you distribute it to someone else, she is then free to run it for her purposes, but you are not entitled to impose your purposes on her.
In the GNU project, we use copyleft to protect the four freedoms legally for everyone. We believe there are important reasons why it is better to use copyleft. However, noncopylefted free software is ethical too. See Categories of Free Software for a description of how “free software,” “copylefted software” and other categories of software relate to each other.
Proprietary software uses restrictive software licences or EULAs and usually does not provide users with the source code. Users are thus legally or technically prevented from changing the software, and this results on reliance on the publisher to provide updates, help, and support. (See also vendor lock-in and abandonware). Users often may not reverse engineer, modify, or redistribute proprietary software. Beyond copyright law, contracts and lack of source code; there could be additional shenanigans keeping users from exercising freedom over a piece of software, such as software patents and digital rights management (more specifically, tivoization).
What if there were a worldwide group of talented ethical programmers voluntarily committed to the idea of writing and sharing software with each other and with anyone else who agreed to share alike? What if anyone could be a part of and benefit from this community even without being a computer expert or knowing anything about programming? We wouldn’t have to worry about getting caught copying a useful program for our friends—because we wouldn’t be doing anything wrong.
If you try to do the work on your own, or simply use the lead management system you have to generate new leads, you will save yourself from potential wasting money buying leads. Especially if you can find success on your own converting leads, there is really no need for you to spend money by purchasing leads that might not be guaranteed to make a sale. If you can do it alone, you might as well put in the extra effort and use your resources to go it your own way.
Freeflys: Another strong contender in the freebies space, Freeflys has appeared on NBC’s Today Show, The Doctors, Fox News and a handful of other media outlets. Similar to most of these sites, Freeflys utilizes email alerts to tell users about free-sample offers as they happen. The site also allows you to search for a specific product with the handy search bar.
