Many years ago I became a regular donor to the open source community of which Mozilla is a big player however, over the years I have been increasingly disappointed by the biased direction of home page content.
Down thumbing obviously biased content recommendations that I consider offensive to my intelligence does nothing to reduce the frequency nor amount of said content. I suspect the selection process censors every conservative source and viewpoint as evidenced by the total absence of those very sources and viewpoints.
Therefore, I have unchecked the "Support Mozilla" and "Recommended Stories" boxes on the "Settings"/"Home" page in order to end my support for those who sponsor bias and remove the propaganda from my Home page. Furthermore, I am discontinuing my monthly donation to Mozilla until such time as the suggested content presents a better balanced and more evenly moderated climate.
