Okay, I can certainly see that perspective and, after reading the link posted by @ayyy@sh.itjust.works I can see how this scale is problematic in other ways since news bias isn’t one-dimensional.
Is there a better way to educate people about the bias of particular new organizations, though? It seems unreasonable to expect everyone to develop their own individual assessment of every news organization. There are simply too many of them offering too many different spins. This attempt at providing something easily digestible seems like a reasonable starting point. It’s certainly not perfect and has a lot of room for improvement but is it worse than nothing?
