All three had rotted past honest usability: - Douyin's upstream (yzfly/douyin-mcp-server) is archived and required a 4-step manual local-server setup nobody could complete - Weibo depended on an unmaintained personal fork (mcp-server-weibo) - WeChat full-article reading was increasingly blocked by anti-bot (#339) while doctor still advertised it as zero-config Removes the channel files, installers, skill routing/trigger entries, reference sections and README rows (zh+en). Honest counts: 13 platforms, 6 zero-config. They can return when maintained upstreams exist. Follows the v1.4.0 precedent of removing Discord/Toutiao (#234).
