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.
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.
Rules that “if you make your version available in this way, you must make it available in that way also” can be acceptable too, on the same condition. An example of such an acceptable rule is one saying that if you have distributed a modified version and a previous developer asks for a copy of it, you must send one. (Note that such a rule still leaves you the choice of whether to distribute your version at all.) Rules that require release of source code to the users for versions that you put into public use are also acceptable.
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.
Notes created in this simple but powerful app are automatically stored online (you need a Simplenote account to use it). Multiple versions of notes are saved when changes are made, in case you need an old copy. It supports markdown for formatting text a little better, but best of all works with a lot of top-flight downloadable desktop note-taking tools like ResophNotes for Windows and Notational Velocity for the Mac.
Content marketing seemed like a viable option only a few years ago to help businesses grow their databases. However, research shows that engagement is getting harder to keep and that a small minority of content online is responsible for the majority of social media shares. If a marketer wants to make content marketing work for their business, they need to produce exceptional content.
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.
Mozilla's email client extraordinaire has jumped to version 45, but it still has all the features that made it great: account setup wizards, multiple languages, hundreds of add-ons, a tabbed interface, great search, junk mail and phishing tools, and the option for a personalized email address with your own choice of a domain name. Migration from previous versions is a breeze and worth it if you're on the desktop.
Another playbook from the last few years, marketing automation, has proven harder to make work for businesses as more companies look to invest in messaging bots to drive more personal connections. These changes mean marketers need to invest time to make their marketing work. Trends show it is only going to get more difficult to keep producing leads using the playbooks from yesterday.
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.
