For those, who is too lazy to open a link: many years ago YouTube stuff announced that their service will not support Internet Explorer 6 so people have to update it at least to IE 8.
It is not a secret taht Google is willing to get a complete dominance over the entire internet but who da fuck cares about the internet explorer? This is a browser, that was made just for downloading the other browsers. Anyone really cares about it?
I prefer to read your summary instead of that long article because it has been established that there are a lot of Google conspiracy for them to rule the internet, honestly, I don't care about these conspiracy theories, as long as they can give me all I want whenever I want to search kinds of stuff using their search engine.
