The lack of compatibility of Internet platforms and even the phenomenon of "link shielding" give many users a headache. Internet enterprises should have served users, but the "shielding external chain" driven by market competition has added a lot of trouble to users. The Ministry of industry and information technology recently guided the governance of the problem of "shielding the external chain" of Internet platforms, broke the "invisible barrier" between Internet giants, and strive to return to the essence of "interconnection" of the Internet. How did the problem of "shielding the external chain" arise? This is the choice for Internet companies to maximize their interests. "Fat water does not flow to outsiders" is the operation logic of this practice of Internet companies, because once the external link entrance is opened, it means that the traffic advantage of its own platform "makes a wedding dress for others". However, market competition cannot be at the expense of user rights. A free and open Internet environment cannot allow Internet giants to "block". Where is the harm of "shielding the external chain"? Normal access to legal websites is the "basic operation" of the Internet world. Now sharing links with friends needs to go through "layers of checkpoints". Restricting external links without justified reasons will not only affect the user experience, damage the rights and interests of users, but also disrupt the market order. Some platforms under "Internet giants" have long had certain public service attributes, and "shielding the external chain" carries out exclusive competition. Content information can not reach users faster, which affects social efficiency to a certain extent. How do regulators deal with it? The Ministry of industry and Information Technology launched a special rectification action on the Internet industry this year, and blocking website links is one of the key problems in this rectification. "The website links of the same type of products or services shared by users shall be displayed and accessed in the same form", "after users click on the external website links, they shall be opened directly in the form of pages in the application", "no additional operation steps shall be added to the website links of specific products or services"... A series of compliance standards shall be released to effectively promote the planned Carry out targeted rectification and implement the rectification action from "paper". Interconnection is the inevitable choice for the high-quality development of the Internet industry. Allowing users to use the Internet smoothly and safely is also the direction that the Internet industry must strive for. In the market economy, the competition among enterprises should be the level of science and technology, user experience, management level, etc. if they deviate from the track and compete on building a "wall", it will be harmful to the enterprise itself, the innovation atmosphere and economic vitality of the society. Only when the Internet platform is unblocked can it really show its strength, continuously refine technology and improve services in more full competition, and promote the formation of a good Internet development environment.
