Interesting. I wonder if they're just using browser extensions though to get the same functionality? Since if you have any browser plug-ins installed (e.g. AdBlock), you've got the same potential issue.
Here I will defer to everyone else who knows more about APP than I do; that one tidbit I brought up was related to me by an HN-phobe who didn't want to say it themselves. :)
In general though I think we'd be better off with Google just adding more restrictive OAuth scopes and improving their logging functionality so that users can see how apps are using their data. I'm clearly biased since my app is built on Gmail OAuth, but I generally just think that for whatever issues OAuth has, pushing people toward browser extensions or IMAP is a step in the wrong direction.
