It doesn't seem to obviously be limited to open source software? The article suggests the illegality comes from the lack of a signed contract, which you don't get with any software under a proprietary EULA either. I assume this just gets ignored though... Most of the rest of the article seems to be about this Romanian tender business, but excluding free software from that wouldn't actually make that software illegal, so it's apparently not really relevant to the title.
