I assume it is true that Google’s video-hosting platform,YouTube, silently removed the accounts of the Al Mezan Center for Human Rights, Al-Haq, and the Palestinian Center for Human Rights in early October. The channels contained more than 700 videos documenting alleged human rights violations committed against Palestinian by Israel. According to “International Business Times” (a slightly left-leaning American online newspaper), YouTube spokesperson Boot Bullwinkle stated that Google is committed to complying with applicable sanctions and trade compliance laws. However, critics argue that Youtube’s actions go far beyond legal compliance. Katherine Gallagher, a senior staff lawyer at the Center for Constitutional Rights, insisted that “Congress did not intend to allow the president to cut off the flow of information to the American public and the world — instead, information, including documents and videos, are specifically exempted under the statute that the president cited as his authority for issuing the ICC sanctions”.

According to AllSides Media Bias Chart, news outlets like International Business Times or The Intercept (YouTube Erased 700 Videos of Israeli Human Rights Violations) are considered slightly left-leaning. I also searched for reports from outlets classified as centrist, but I could not find any addressing this topic. Nevertheless, I am fairly confident that the claim is true.
