We share a commitment to free knowledge and work together with our community.

The Wikimedia Foundation is the nonprofit that hosts Wikipedia and our other free knowledge projects. We want to make it easier for everyone to share what they know. To do this, we keep Wikipedia and Wikimedia sites fast, reliable, and available to all. We protect the values and policies that allow free knowledge to thrive. We build new features and tools to make it easy to read, edit, and share from the Wikimedia sites. Above all, we support the communities of volunteers around the world who edit, improve, and add knowledge across Wikimedia projects.

קרן ויקימדיה קוראת לאפשר חיבור לאינטרנט, וגישה לידע, בלי הפרעה בעזה
קרן ויקימדיה מביעה את דאגתה העמוקה ממקרי ניתוק האינטרנט הנמשכים ברצועת עזה, הפוגעים באופן ישיר ביכולתם של אנשים לקבל ולשתף מידע מוויקיפדיה וממיזמי ויקימדיה אחרים. בתור המלכ”ר המארח את מיזמי ויקימדיה, הקרן מאמינה שמקרי הניתוק האלה מאיימים על משימתנו לשתף ידע ברחבי העולם ולהגן על הגישה לידע כאחת מזכויות האדם.
