I think it is the opposite. WeChat doesn't require Chinese phone number, Bilibili/Weibo/Kuaishou/etc don't either. Some allows log in through WeChat. Douyin is the only one I came across that you have to have a Chinese phone number.I hope the Chinese government is watching this latest development carefully, and realize the potential benefits of making certain Chinese apps less restrictive (right now almost all apps need a Chinese phone number).
