I also have stopped donating. I replied to a WM Foundation email explaining why and they said they don't have editorial control over wikipedia, i.e. their hands are tied. Well OK, but I'm not giving money to fund the promulgation of Jew hatred and blood libel. Sad state of affairs! I've given for years.
I hope The Wikimedia Foundation can get its act together, and I admire the courage of Jimmy Wales for speaking up about this, but I've also stopped donating. I want no part of this.
