interesting question. Maybe I am unknowingly spouting propoganda. Looked it up. Its true over 80% of the time, but I thought that number would be higher. Theres a chart midway down the page if you want a TLDR

the domiannace of the big news outlets by zionists is well documented.
notice how Israel has killed all the journalists and the sites that do report carefully use passive lagnuage for israeli actions and active and adverserial language for anything lebanese or gazan people do. Its obvious bias and controlled jouranlism. So why would you think them not covering something is meaningful?
Maybe you are just lookinbg for confirmation of your own bias?
