In the startup space it's common for a founder to, after a successful launch, hand off control of the organization to someone else who's better equipped to drive the company in slow and steady mode. If the people in charge of the Internet Archive feel like they're best equipped to be revolutionaries rather than maintaining the ground they won in the past, maybe it's time for them to transition into a new organization and hand off the IA to people who are able to run it in maintenance mode.
Now that's sad, I hope they learned their lesson, and I think we should all step up to help defend them. Aside from donations, I think people should be making a large amount of noise at their elected representatives to start reforming the ridiculous IP framework in the United States. The whole point of copyright and other protections was to ensure that there was some incentive to people to produce content and be able to monetize it. I think it's ludicrous to suggest that you need such an utterly long period with a shark full of teeth to go after people in order to incentivize the producing of content.
