Microsoft's strategy for interacting with Open Source seems to be settling into the pattern of treating it like any other software. Instead of being pro-"Open Source" or anti-"Open Source" their reaction depends on the specific project.

Software that interoperates with, extends, runs on, or otherwise boosts Microsoft products: Good.
Software that replaces or competes with Microsoft products: Bad.

So, it would make perfect sense to Microsoft for them to try to lure open source projects built on top of OpenOffice.org, like plugins or whatever, to switch to building on Microsoft Office instead.

Exactly: not complying, getting dragged to court, and paying is an option. You're not obligated to open the source, you can just suffer the consequences of copyright violation instead.

I agree that that's not nice. But - this is the key point - he is winning the zone for his team. His actions contribute to fulfilling his objective within the game, and they are legal by the rules of the game.

It sounds to me that the entire purpose of the PVP zones is to have PVP fights, and people who aren't there to fight or interact with enemy players are abusing them for something contrary to the designer's intent. If someone comes along and does something mean to them, that's their fault for being in the PVP zone. If the designers wanted to provide a place where you can get the increased experience without the risk of having someone kill you they would just add it!

You're confusing speculation on futures contracts with speculation on actual items.

Take the case of tulips. Speculators buy physical tulip bulbs and hoard them, driving the price up, causing more people to buy tulip bulbs, etc.

The same thing happened in the housing market - people were buying houses, not to use or rent them, but just to resell them later.

For that to happen in oil, speculators would have to actually buy oil and sit on it waiting for prices to go up. But for the most part, the speculators never actually touched a drop of oil. They bought futures contracts, and resold them before they came due. They weren't actually taking the oil off the market, so they couldn't cause a bubble.
