Reminds of that time someone invented dropbox, and one of the top comments was "For a Linux user, you can already build such a system yourself quite trivially by getting an FTP account, mounting it locally with curlftpfs, and then using SVN or CVS on the mounted filesystem. From Windows or Mac, this FTP account could be accessed through built-in software."
Totally irrelevant. The response to Dropbox you describe was "meh, easily done with existing tools". The analog hole response is "no app can provide what users would assume this app provides"
I think the comparison to Snapchat is more relevant: Snapchat is expected to provide only temporary access, but cannot guarantee that. This did not impede snapchat's growth, and might not really be an issue for rumuki; however, the use context is different so the comparison is not very informative.
To my mind it's a bit different in that this guy is saying the software can't actually guarantee what it's supposed to, and not that it could be accomplished with more trouble.
