Is movable type open source free?

Sorry for such a basic question, but I can't find a solid answer elsewhere. I read that movable type is now open source, but does that mean it is now free to commercial users? If not, can someone explain what exactly does it mean to now be open source vs. past versions that were not. If so, does anyone have a link to download the free version?

Actually, that is the info I was reading that confused me in the first place. When you click on the download link, it says free for personal use. I still don't know for sure if it is free for commercial use. I thought open source meant you could use it for either purpose, but then when you try to download, it says free for personal use.

Open source doesn't even mean it is free. It simply means that the source code is available, openly.

You need to see what kind of license it has, and read the license. It may have it's own unique license, or may use one of several common licensing models.

At minimum, by definition, the license would have to permit you to download and examine the source code. If it permits nothing else, then it is still "open source".

The minimum is uncommon, but has it's uses. For example, imagine a commercial cryptography application. The manufacturer might want to make the source code freely available to experts world-wide to verify that it does what it says and is not flawed. But they still may require payment for any use of the application. (Except, perhaps, for testing it for flaws, backdoors, etc.)

I think slashdotters coined the phrases that most accurately make the distinction:

"Free as in beer"
"Free as in freedom"

A package can be free as in beer (e.g. cost-free) or free as in freedom (you are free to look at it, perhaps to alter it), both, or neither.

A free-of-cost package may or may not be open-source.
An open-source package may or may not be free of cost.

that will consist of a GPL-licensed version of Movable Type 4.0, to be released in Q3 2007

There are three licenses (or there will be, once the open source version is out). Open Source (MTOS), Personal and Commerical. Personal is free for personal use and will remain as such. Commercial has always required payment. MTOS is not the same as the personal code, is released later, and can be used for any kind of commerical or non-commercial site.

Thanks for the replies. I read some of the comments on the link above and yes, the Open Source will be free, but it has not been released. It will have features different than the pay version, but the differences have not been announced. It can be used for commercial purposes.
