no one is saying anything "magically" happens. The profit-taking has happened and will continue to happen - there are a finite number of shares to be purchased, yet shares are still being purchased by shorts. There is room for profit-taking at every cost basis except for the very top - looking at that subreddit, there are no illusions that it will literally last forever, only that selling en masse now (when shorts are actively working together to fight back) undermines the squeeze.
