I believe Yinxiang Biji was spun out of Evernote proper and they run independently (of which Evernote is a minority shareholder), so it's not a correct comparison. (Source: https://techcrunch.com/2018/06/07/evernote-is-spinning-out-its-chinese-business-and-it-plans-to-take-it-public/) I think it's great that they have added mind mapping functionality to YB; I'm a big fan of mind mapping, generally. We lost the inimitable Dr. Tony Buzan earlier this year. However, if you'd like Evernote to progress, might I suggest making a feature request (see the link below in my signature on how to do so) and not insulting the hardworking people behind the service. We can all disagree and rigorously debate the progress and direction of Evernote, but ad hominem attacks are pointless.
By the way, if anyone knows differently about YB's current status, I'd be curious to know.
