Well, he alleges that Square cancelled his account without notice, and describes how that affected his business because he had made efforts to drive customers to use the Square payment method. He also admits that he should have developed a more robust solution, but rationalizes that he stayed with Square due to good prior experience. Even if Square is perfectly in the right based on their user agreements they may be throwing good money away, and chasing off good customers. It's not hard to understand why a retail business owner would appreciate a little notice before an account cancellation.
