Core Viewpoint - The recent adjustments to 123 Cloud Disk's free user rights focus on "traffic limits, functionality restrictions, and encouraging paid subscriptions," significantly increasing costs for ordinary users while aiming to combat resource abuse [1][2][13]. Summary by Sections Free Traffic Reduction - The free monthly download limit has been drastically reduced from 30GB to 10GB, representing a 67% decrease [4]. Excess Download Charges - Users exceeding the 10GB free limit will incur charges of 0.05 yuan per GB, with a minimum charge of 0.5 yuan for any download under 10GB [7]. Visitor User Changes - Unregistered users (visitors) must now pay 0.1 yuan per GB for downloads, with no free allowance [8][9]. Streaming Traffic Charges - Streaming audio and video files will now consume part of the 10GB free limit, meaning high-definition content can quickly deplete available traffic, leading to additional charges if exceeded [10]. Share Traffic Package - The sharing traffic package remains, allowing file downloaders to not use their own traffic if the file sharer has purchased this package [11]. Reasons for Adjustments - The adjustments are primarily aimed at curbing resource abuse by free users who exploit the system through bulk account registrations and high-frequency downloads, which have led to increased server costs [13][15]. - The company has reported that as of September 2024, registered users approached 50 million, indicating significant user growth but also highlighting the imbalance in the revenue model due to a high proportion of free users [13][14]. - The cloud storage industry is facing similar cost pressures, suggesting that such traffic limitations may become a standard practice across the sector [15].

New Traffic Charging Scenarios - Streaming audio and video files will now consume part of the monthly free 10GB limit, with high-definition video playback quickly depleting this allowance [8]. Retention of Sharing Traffic Package Mechanism - If a file sharer purchases a "sharing traffic package," others downloading that file will not use their own traffic quota, as the cost will be borne by the file sharer [9]. Reasons for Adjustments - The adjustments aim to combat resource abuse by free users who exploit bulk account registrations and high-frequency downloads, leading to increased server costs. The company has reported that its registered user base approached 50 million by September 2024 [11][12]. - The overall tightening of policies is attributed to cost pressures from user growth and an imbalance in the profit model, with a high proportion of free users and insufficient conversion to paid subscriptions [13].
