The builtin rating is absolutely horseshit, that needs to go. If I want my TL;DR (summary) to contain opinions, I go read the news.
I don't understand how a website telling me that Facebook has a "Grade E" ToS is supposed to help me at all. Just give me a summary, the bullet points -- you don't need to try to assign each into "good/bad", and you certainly don't need to run an "algorithm" to show me if it's good or bad.
Chances are, if it says "sells all your data", I can figure out if I care about that, as a user, with freedom.
Maybe give me what you think (or your algorithm thinks) are the most important/controversial/impactful points, but don't rate them. This is akin to Wikipedia saying "Friday is the worst song ever created, wow it's so bad (thumbs down emoji)".
