Apple’s updated business terms for EU developers introduce three major changes: the ability to use alternative payment systems outside Apple’s In-App Purchase, stricter child safety rules for these new payment options, and expanded eligibility for distributing apps through third-party marketplaces or directly via the web. For European customers, this means more payment flexibility, potentially lower costs, and a wider selection of apps from diverse sources, though it also requires greater vigilance regarding app security and the trustworthiness of non-App Store sources.
