I don't know if it's clear from the title and the post and it could be that everyone already knows this, but I'll just restate it anyway.
Idiling won't get you less items then someone playing the game. They just capped the number of items you get over some period. The article suggests that 1 hour a day is about the time you get items. So idiling after that period gets you nothing and the cap is low enough that an idiling player will get about the same number of items someone who plays normally gets. People who play 50 hours a week normally lose out but they're in the minority.
