1. Vulnerabilities are fixed relatively quickly. 2. Free software is a matter of the users' freedom to run, copy, distribute, study, change and improve the software. 3. For things released as free software, if the company that makes the software goes out of business, the software lives on, instead of you suddenly having to invest major bucks in another product and the migration to that product. 4. You never have to worry about the company that makes the free software hiking your license fees 500% in a 2-year period like some other company that we won't mention has a habit of doing. 5. Free software tends to be more reliable than non-free software, due to the lack of deadline pressures that allow more thorough bug-fixing and bug-checking, and the larger pool of potential beta testers that allow detecting bugs before an actual release. 6. If there's a bug in free software, you can either fix it yourself, or hire any programmer on the market to fix it. You don't have to beg MegaCorp to please, pretty please, fix that bug, please?! (And the bug doesn't get fixed for years, if ever). 7. If a new revision of your operating system is released, you can re-compile Open Source against that new revision to take advantage of its new features and to insure full compatibility between the Open Source application and the new revision of the operating system. For closed source, if the vendor doesn't upgrade your application and it doesn't run on the new version of the OS... you're S.O.L., sorry. 8. You never have to ask permission to use Open Source in novel ways, such as providing access to an Open Source program via the Internet so that your remote salespeople can run it without having it installed on their own laptop computers. With proprietary programs, if the vendor doesn't offer licensing terms that match your needs, sorry, you can't do it.
