The Internet Archive is also a profoundly worthwhile charity. But those of us with a little understanding of the space would be remiss to not point out that this article is dishonest and you're falling for it. It isn't uncommon for nonprofits (and Wikipedia is not only a nonprofit but is functionally infrastructure at this point; its survival is important beyond its own self-perpetuation) to try to build up an endowment in order to survive lean times. This is normal. You're falling for an okeydoke. Please don't.
