Freeware

Some Software products are “free” to use, like Adobe Acrobat Reader, or Apache HTTP Server.

Not everything that is Freeware is also Open Source. I.e. Apache HTTP Server is Open Source, where Adobe Acrobat Reader is not.

Not everything that is Freeware is actually free. Especially as an enterprise like Open Ecosystems one should be very careful before one decides to use Freeware, even Open Source Freeware. The most important reason is that Freeware comes with a Software License. Some of them require you to make your code Open Source as well, if you decide to use the Open Source product. Depending on the use case that could prove detrimental for the company.
