Echoes of the underwater world

I was playing a bit with the PicLens Firefox extension today and I realized that they are basically shipping FFmpeg. There is a libs directory in their extension that contains avcodec-51.dll and looking at symbols of that dll clearly shows decoding functions for VP6, VP5, H.264 etc..

Is it me or startups nowadays just don’t care about patents and licensing at all when it comes to proprietary formats ?

I am about to buy a revolutionary water treatment system called Wellan 2000 but I am absolutely unable to understand how it really works.

If someone who understands a lot about physics would be so kind to vulgarize this system for me in a comment, I’d be grateful !
