If they work for Linux, providing a Free stack for multimedia and multimedia streaming and DVR functionality, then yes. Yes, I do. Your "throne" exaggeration is a bit extreme, though. I thank Google for their work on Chrome, although whether their patent license extends to you if you build Chrome and ffmpeg is murky at best (see also Fluendo and their MP3 plugin proprietary vs BSD-licensed). That's why I asked MPEG-LA for more information.
I also buy Codeweavers Crossover Office because they help Wine to a great degree.
"Do you also thank Adobe for "legally licensed" Flash"
I thank them for having a Linux plugin. I don't like Flash over Free, patent-free standards, though. (See also the "I produce Theora content") I'm doing my part to keep us viable now (Fluendo and their plugin work) and in the future (Fluendo's Free software, Theora/Xiph, and my FSF membership).
and Microsoft for "legally licensed" Windows 7?"
If I ran Windows, I'd thank them for licensing the codec.
You do nobody any favors when your patent protection plan is the equivalent of burying your head in the sand, putting your fingers in your ears and saying "There ain't no patent threat" three times fast. You counter it by helping establish Free, patent-free standards and filling the gap until we get to that point.
