Software patents are valid in multiple jurisdictions. You might not like it, but I don't like a 70mph speed limit on UK motorways either. Anyway, I'm sure the users who don't find jacekowski's repository, or those who want Chromium if he ever disappears (as so many people have before), will appreciate the moral stance ;-)

Anyway, since Maemo uses apt as an update distribution mechanism there's certainly no use for Courgette in the Maemo version of Chromium. Whether or not that's easy to remove from both source and binary is not something I've looked in to (it seemed more appropriate a question that the maintainer would be able to answer).
