None of this changes that what you said was wrong.
Facebook was launched before WoW. Period.
Other social media existed before Facebook and before WoW. Period.
They were popular for their time. Doesn’t matter if they were as popular as WoW. The popularity was not the point anyway. You tried to claim that WoW was one of the few places to offer cross-country play or to offer a place for people to make friends online. That is either a lie or an ignorant statement. People had already been connecting around the country and around the world well before WoW or the 2000s, both in gaming and outside of gaming. This was not “groundbreaking” for the 2000s, as you claim. It was already present in the 90s. Nor was the concept of making friends online groundbreaking or unique to the 2000s or to gaming. People had been doing that even prior to the 90s.
You might have an arguable point with the 2008 financial crisis playing a part in WoW’s peak subscriber numbers during Wrath, but that is questionable because the 2008 financial crisis built up and burst during middle and late BC. Not Wrath. In fact, the peak Wrath numbers didn’t happen until 2 years after the financial crisis.
