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.
“Free software” means software that respects users' freedom and community. Roughly, it means that the users have the freedom to run, copy, distribute, study, change and improve the software. Thus, “free software” is a matter of liberty, not price. To understand the concept, you should think of “free” as in “free speech,” not as in “free beer”. We sometimes call it “libre software,” borrowing the French or Spanish word for “free” as in freedom, to show we do not mean the software is gratis.
This re-labeling has since attracted a lot of support (and some opposition) in the hacker culture. Supporters include Linus himself, John "maddog" Hall, Larry Augustin, Bruce Perens of Debian, Phil Hughes of Linux Journal. Opposers include Richard Stallman, who initially flirted with the idea but now thinks the term "open source" isn't pure enough.
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.

This could be the most high-end free software ever: it's the very tool used to render the images you see in Pixar's movies. That's because RenderMan was developed by Pixar in-house for that purpose, but became free for non-commercial use. It's not going to do you much good without other software such as Autodesk's Maya for creating 3D models. But budding artists and filmmakers will want to take note. You'll need a 64-bit system to run it.

Foxit Reader is free for not just reading, but also creating PDFs and collaboration on the files (at least you can with the Windows version; Mac and Linux are more limited). Foxit's MobilePDF apps are on iOS, Android, and Windows Phone. What's more, they support a tech called ConnectedPDF so you can send PDF files and even update them after you send them (thanks be to the cloud).
Free Software is the original term for software that respects freedom, and there are important reasons why this terminology continues to be used today. Free Software connotes freedom, and when translated there is a clear distinction between freedom and price. In French, Free Software becomes "logiciels libre", "software libre" in Spanish, "software libero" in Italian, and "Fri Software" in Danish.

Commenting on Websites: Sites like Huffington Post, Entrepreneur and Forbes all rely on social media sign-ins. This means when you comment on these sites; you are logged into another site and posting as that profile. You can find the hottest articles, read the comments and connect with the commenters on their respective social media profiles. It’s one of the easiest ways to find leads. 
Too often a business will invest solely in how-to type of content. If you are a social media software company, you may invest in how-to posts as new social media tools become available. These posts can be super helpful, and a business may end up ranking high on search engine result pages (SERPs) with a how-to piece of content. The problem is that there are hundreds of businesses writing the same posts, so the pool of competition is quite large. Secondly, these posts don't age well. Snapchat might update their context cards next week, which would mean marketing teams need to update their posts with new information and new screenshots.
Since free software may be freely redistributed, it is generally available at little or no fee. Free software business models are usually based on adding value such as customization, accompanying hardware, support, training, integration, or certification.[18] Exceptions exist however, where the user is charged to obtain a copy of the free application itself.[51]

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.
