These articles exist because some questions are too long for a chat. Each one takes a question that keeps arriving, answers it in the first paragraph for anyone in a hurry, and then does the work underneath for anyone who wants it. Where an answer depends on your connection, your hardware or your country, the article says so rather than pretending there is one number that fits everybody.
Nothing here is a review round-up and nothing is a scoreboard. When a piece quotes a figure, the arithmetic behind it is on the page so you can run it against your own bill, your own allowance and your own evening.
