The opposite of file recovery is utter destruction—the kind of thing you do to keep a file out of someone else's hands. Eraser does just that, writing over the spot where the file(s) lived until it's scrubbed clean, with no chance of coming back to haunt you. You can even use it to schedule a wipe of the free space on the disk, or just to purge your recycle bin. During setup you get the option to install an extension for Windows Explorer so you can wipe files or free space instantly.
In 1983, Richard Stallman, longtime member of the hacker community at the MIT Artificial Intelligence Laboratory, announced the GNU project, saying that he had become frustrated with the effects of the change in culture of the computer industry and its users.[27] Software development for the GNU operating system began in January 1984, and the Free Software Foundation (FSF) was founded in October 1985. An article outlining the project and its goals was published in March 1985 titled the GNU Manifesto. The manifesto included significant explanation of the GNU philosophy, Free Software Definition and "copyleft" ideas.

It's a little awkward, so we'll get straight to the point: This Monday we humbly ask you to defend Wikipedia's independence. We depend on donations averaging about $16.36. But 98% of our readers in the U.S. are not responding to our messages, and time is running out to help in 2018. If everyone reading this gave $2.75, we could keep Wikipedia thriving for years to come. The price of your Monday coffee is all we need. When we made Wikipedia a non-profit, people warned us we'd regret it. But if Wikipedia were commercial, it would be a great loss. Wikipedia unites all of us who love knowledge: contributors, readers and the donors who keep us thriving. The heart and soul of Wikipedia is a community of people working to bring you unlimited access to reliable information. Please take a minute to help us keep Wikipedia growing. Thank you.

With names like Writer, Spreadsheets, and Presentations, you might not think that Kingsoft's WPS Office has a lot of imagination. Who cares? They work great and are all part of one program, not three separate pieces of software. The free version seems to do it all, mimicking the look of Microsoft products, even with a ribbon interface. It also comes with 1GB of cloud storage and has mobile versions for phone- or tablet-based edits. You'll have to view some ads to use it for free. It also offers a PDF to Word Converter Tool for Windows and Android.

Proprietary software on the other hand tends to use a different business model, where a customer of the proprietary application pays a fee for a license to legally access and use it. This license may grant the customer the ability to configure some or no parts of the software themselves. Often some level of support is included in the purchase of proprietary software, but additional support services (especially for enterprise applications) are usually available for an additional fee. Some proprietary software vendors will also customize software for a fee.[52]

Microsoft CEO Steve Ballmer stated in 2001 that "open source is not available to commercial companies. The way the license is written, if you use any open-source software, you have to make the rest of your software open source."[55] This misunderstanding is based on a requirement of copyleft licenses (like the GPL) that if one distributes modified versions of software, they must release the source and use the same license. This requirement does not extend to other software from the same developer. The claim of incompatibility between commercial companies and Free Software is also a misunderstanding. There are several large companies, e.g. Red Hat and IBM, which do substantial commercial business in the development of Free Software.
