With your own reply you show that they have given you most of the information needed to make your own assessment. Like I’ve said other places in this thread, you don’t have to agree with them. I have never claimed they are correct. I’m saying that they provide information about how they arrived at their conclusion, you can assess that information and decide whether you agree.
It still stands that it is at least a reasonable place to look to gather basic information about a media source. And provides you with a solid starting point to research and make an assessment about a news source.
I agree that using the US political spectrum pretty significantly skews things since US politics is almost all center to right if you compare it to the wider spectrum globally. But since they gave their information, and what spectrum they are using it makes it pretty simple to get a baseline for most media outlets at a glance if it’s not one I’m familiar with.
And with the number of outright insane news sources people like to share, it’s useful to have a way to get at least a decent snapshot of what to expect.
