Summary of what this is actually about...
Yes, that's all in the article.
It's still newsworthy, because this confirms that there won't be any Blizzard games on Steam for quite some time.
The reason is this: Blizzard was owned by Vivendi, which also owned Sierra. This legal battle was between Sierra/Vivendi and Valve (HL1 was published by Sierra, HL2 by Vivendi). This continuing fight was the reason why no Sierra/Vivendi/Blizzard games where published on Steam. On the other hand, Activision had loads of games on Steam and was one of the first publishers to embrace it.
So when Activision and
Vivendi Games (including Blizzard and Sierra) merged, I had hoped that all those stupid Sierra/Vivendi* execs would be fired and replaced by the ones of Activision and that this would also settle the fight with Valve and therefore allow Blizzard games on Steam. But it seems that this didn't happen.
*You know those guys have to be extremely stupid when you look at what they did to Sierra, one of the most influential developers and publishers in the 'early days' of computer gaming. They seem to have made no single good decision since 1998.
It's all just business. Once they solve this suit, everything will be back to normal. There's no hidden hate behind all this that would prevent Blizzard from publishing on Steam. The guys there aren't idiots; It's obvious that Steam can make even ancient games sell like strawberry cake. Just pop in a 50% off on something that barely sales anymore as you put it on steam and bam, there's a million dollars profit. For both. Getting on Steam means that you suddenly get a huge userbase and an already established system of game distribution. It's win-win if they get on steam, and lose-lose if they don't. It's just a matter of time.
For the sake of example, let me remind everyone of Abe's oddysee. An old classic, got on steam, few percent off, bang, best selling game for the next 5 days.
