The FSF list is not prescriptive: free licenses can exist that the FSF has not heard about, or considered important enough to write about. So it's possible for a license to be free and not in the FSF list. The OSI list only lists licenses that have been submitted, considered and approved. All open-source licenses must meet the Open Source Definition in order to be officially recognized as open source software. Free software on the other hand is a more informal classification that does not rely on official recognition. Nevertheless, software licensed under licenses that do not meet the Free Software Definition cannot rightly be considered free software.
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.
Everyt business runs on opportunity. It runs on the potential of the new prospects that could turn into paying customers. These incoming prospects are called sales leads and they hold a strong place in the success of a company. So today we ask whether or not buying sales leads is the right decision to help your company grow, or if free sales leads are the way to go. Let’s look into the basic terms before we dive into the whole ordeal:

Although both definitions refer to almost equivalent corpora of programs, the Free Software Foundation recommends using the term "free software" rather than "open-source software" (a younger vision coined in 1998), because the goals and messaging are quite dissimilar. "Open source" and its associated campaign mostly focus on the technicalities of the public development model and marketing free software to businesses, while taking the ethical issue of user rights very lightly or even antagonistically.[19] Stallman has also stated that considering the practical advantages of free software is like considering the practical advantages of not being handcuffed, in that it is not necessary for an individual to consider practical reasons in order to realize that being handcuffed is undesirable in itself.[20]
Ubuntu updates yearly, once majorly and once with just fixes. But each iteration brings new tools and developments. Last year the Linux distro even made the leap to tablets; that after trying to power smartphones in 2015. The latest version for desktops and laptops comes with a full suite of software (including LibreOffice), access to thousands more (and many free—just look for the penguin icon throughout this story). It's the Linux of choice here at PCMag, for it's one that is easy to master by just about any user.
And, we should explain publicly the reason for the change. Linus Torvalds has been saying in "World Domination 101" that the open-source culture needs to make a serious effort to take the desktop and engage the corporate mainstream. Of course he's right -- and this re-labeling, as Linus agrees, is part of the process. It says we're willing to work with and co-opt the market for our own purposes, rather than remaining stuck in a marginal, adversarial position.
