From the article
on The Register, perhaps it is not as bad as it sounds:
However, Melbourne was keen to stress that the company (Ironstone) isn't going to put the squeeze on the many fan sites. Non-commercial sites will be allowed to continue just as they are, he pledged. "The C64 has only stayed alive because of the fans," he added.
Whilst I'm not supporting what they are doing, they say they're only after the commercial sites, which are making money off a brand they now own. Al least they're not going to try and shut down all the not-for-profit stuff like some greedy organisations would...
What commercial sites are they talking about though? It sounds like the main people who will be affected are the developers who sell (rather than give away) C64 emulators
