Rotten Tomatoes works because (1) its audience generally trusts some (maybe even most) of the reviewers, and (2) some movies are good. I don't see how Rotten Tomatoes for VPNs can work.
Some gems from the top 10:
4. Black Panther
6. Parasite
7. Avengers: Endgame
9. Knives Out
10. Us
Its surely just coincidence that the half of the best films ever made in human history were produced in the last 5 years.
If it sorted by tomato-meter value instead, the esteemed classics would rise to the top, and the entries you took issue with wouldn't even crack the top 50.
Whatever "adjustment" they are doing seems to strongly favor recency.
