Also, just had a thought about the #fortniteboycott. It should last like the whole weekend. Don't just not play #fortnite on March 19th. Don't play Fortnite until next Tuesday. Have the whole weekend have low player counts.
More noticeable that way. If the boycott is only on March 19th, #epicgames can excuse the low player count on, "It is a weekday the season launched. It is a Thursday."

The low sales of the battle pass and the cancellation of crew should hurt as well.
