Facebook or any feed with an algorithm is a manipulator that only shows what is in its interests. The best way to find out the truth is to read the primary source. That’s why I read press releases, watch Eurovision without commentary, find out about metro breakdowns from the metro’s Twitter.
If I need some extra information to better understand something, I google it (yes, Google is also biased, but nevertheless).
RSS is the best way to subscribe to anything, as it is a technology and not a product. Hint hint click click.
