What if Linden could turn a huge movement of thousands of people against their policy to a movement to work with them? The interests of Second Life as a company, and its residents do not have to be in conflict. Any fee increases or resource throttling could be avoided if the right direction is taken.
That direction is to reduce costs by optimizing the way Second Life and simulators work. http://jira.secondlife.com/browse/VWR-8503 describes problems with how SL retrieves assets and manages cashe that could be causing significant problems and system load. A fix for this issue could reduce load (and thus operating costs.) In addition, a transition to HTTP assets could increase speeds and reduce load at the same time. I'm not sure if the establishment of LLNet (http://blog.secondlife.com/2008/10/28/ongoing-updates-from-the-grid-from-fj-linden/) would reduce costs, but if it cuts out networking middlemen it could very well be. Linden Lab has a history of innovation (at times), and taking the approach of putting that innovation to use to cut costs through streamlining seems the best route.
But here's the deal-sealer: if Linden Lab devotes itself to pursuing cuts in operational costs first, they could potentially have the huge amount of resident resources used in the openspace movement instead help them make SL better and more efficient. There's many professional programmers and technologically-minded people in the openspace movement that could be tapped as a sort of think-tank for problem solving, or problem detection via digging through the code. Thousands of other less technical residents could serve to be bug testers on a massive scale, and given the proper tools and instructions, do testing.
In effect, the possibility of the Openspace movement turning their energy into aiding to better second life is a huge carrot at the end of the stick. Not only could this help fast-track new code, but also could help heal the wounds caused by this fiasco by allowing residents to have a meaningful impact. Residents win because in the end, they get a more stable, better platform.
Linden has a huge opportunity at the present. Approached correctly, this could be hugely beneficial for all. It's something to try, at least; Linden could see if the cost-cutting and new resident-collaboration measures are effective in two months, and if they are deemed to be unsuccessful and still deem their costs for openspaces (and resource use) to be an issue, they can re-address new pricing.
