Today I was pleasantly surprised when I saw that cats will support open source again. (link)

By doing this they are coming back from a earlier decision of being open source.

After ehour a few months ago, cats did also turns it back to open-source. :(

They say that they didn't get enough back from the community. (link) Hell, I was even writing a module for it, that would be spread around when finished. So pitty.
