Looking at the page I can easily identify political opinion of the authors and detect view points of who should be given freedom of speech and who shouldn't. Thankfully they do link in small print to the methodology, which explain that the views are that of the Freedom House staff. They do consult others which is a major plus, but in the end its the staff that make a decision about what freedom is, who should get it, and who shouldn't. The biggest criticism I would give the site is the lack of any critical assessment of contested topics where different social scientists has different conclusions.

I give the site a score of 7/10.

This site is unreadable on mobile. Everything in the table has a huge font.

Reporters without Borders ranks the US behind quite a lot of European countries: https://de.wikipedia.org/wiki/Rangliste_der_Pressefreiheit (German Wikipedia because the English article ironically doesn't include data)

"Freedom of Expression and Belief": US, 3/4. Germany, 4/4. Report invalidated.

You have misread the report. In actuality the results are 14 out 16 points for both .us and .de in that category.
