All the actual information, including the risks and the methods for doing so anyways are all already here for anyone to find (even if the search here on Talk isn't the best). It's not about creating a special group of people that hold "the knowledge". It's about making sure that someone that has never had a Maemo device doesn't immediately try something that can harm his device until he at least understands what's going on and the risks he's signing up for. Again, all the info is already shared anyways, so it's not like there's anything actually hidden here, just massively discouraged.
They're maemo and MeeGo... "Meamo!" sounds like what Zorro would say to catherine zeta jones... after she slaps him for looking at her dirtily...
