[User support] Review the "Private bridges cn" (front desk) and /commands (cdr.link)
In our user support documentation, we have included an option for users in China to request a 'private bridge' by emailing us. However, we have been receiving requests for private bridges from countries without heavy censorship, like Mexico, where internet restrictions can be bypassed using bridges from other distributors (https, telegram...). The feedback and emails received may indicate a possible misunderstanding of requesting a private bridge. Some users believe that because censorship in China is so sophisticated, they need "that bridge" to bypass their local censors, which is a misconception.
Let's review and check how we can improve the tb-manual text and the commands in CDR.Link. (cc @ebanam @nina)
