I hope there will be no integration with sponsored providers in K-9. I remember I switched to sylpheed when I figured out Thunderbird was establishing connections to DropBox and promoting it for sharing large files. Perhaps it wasn't DropBox but something else ... Perhaps I'm even making this up (although I don't think so). I've always wanted to know more about this promotion of a filesharing service in Thunderbird, so if anyone knows anything about this, please reply (: AFAIR it was a preinstalled extension on Thunderbird from Debian.
