It is possible I'm not cynical enough, but if I were trying to gain sympathy for my cyborg-prosthetic plight, the more I could relate it to things people are already comfortable with, the better.
I think the simplest answer is the most likely: That franchise has bumped prices up above what McD's corp allows for and/or has figured out a way to game the computers so they are underreporting their revenue and thus are paying much less in franchise fees than they should be. Given its prime tourism spot, people don't complain, but if pictures got back to corporate, there would be problems.
I've been following his work for some years (decades) now, and while he is an "interesting" person, he has made many leaps in both design and tech involved, as well as testing.
All I know is we have three things:
1) A patent for the 'eyetrap' issued in 2003 with another 8 years or so to run.
2) A huge company with > $100B in the bank who has made a big publicity play betting on their technology that, on the surface clearly infringes.
3) No statements either from either party that a license is in place. In fact the Google Glass page should say "this device is covered by patents ..." but it doesn't.
If in fact no license exists, I see a table in the square with between 100M$ and a 1B$ sitting on it with nobody watching. I would not be surprised in the least that someone decided to try and take it off the table.
Time will tell.
Google doesn't have > $100B in the bank (citation: http://finance.yahoo.com/q/bs?s=goog+Balance+Sheet). You are probably thinking of Apple.
I continue to believe that Google is perceived to be a 'high value' target by offensive litigators.
First the original article was deep-linked into the eyetap.org site. Which is to say it didn't appear as a link on the front page, in fact I didn't find any inlinks to it until this story broke and those are from blogs etc. And it was posted by an account created to post that one link on HN (not like Dr. Mann or someone who regularly participates here stumbled across it and tried to link it.)
Now if Dr. Mann had a running blog about life as a cyborg or his thoughts on wearable computing, and this just happened to come up in that blog as "Oh the saddest thing happened ..." then it might feel more natural. It has since been converted to a one-entry wordpress blog.
As I've said elsewhere, we'll see what the next steps are. Eyetap has certainly gotten a lot of publicity out of the deal so I expect the press will follow up on any fallout here as well.
[edit] The current pace of litigation seems to be leading towards some form of Kessler Syndrome - http://en.wikipedia.org/wiki/Kessler_syndrome - but made of patents instead of orbital debris, that will finally result in all courtrooms in the world discussing nothing but technical IP cases.
A cynic might think they were trying to harvest accesses from internal to Google IP addresses so that as of today they could show 'knowable infringement' aka treble damages.
