Because a lot of stuff you read online is made up, misleading, wrong, or even all three. Either on purpose or not. The most insidious stuff is what "seems plausible" but isn't, it's how you get stuff like common myths and misconceptions[0]. Shouting "source?" at every article is not pleasant and may sound annoying, but I think we should respect people who question things (or simply want to dig more) rather than pushing back asking for "why". The pursuit of (true) knowledge in and on itself is something that shouldn't be questioned, especially in this technological age.

Well sure. But how could this number actually be wrong once you think about it?
