Drew would have to kill a baby panda with an elephant tusk for me to even begin thinking about switching.
What I'm more interested in is what HN users like and dislike and recommend, as opposed to a bunch of features charted into a table with nothing valuable in terms of reliability, usability and actual security.
Lately, I've been leaning towards Jungle Disk for file syncing & some S3 solution for cloud backups.
This said: I stand with dropbox on this issue. Abusing their service to fake a p2p is definitely not the way to go and not that clever hack if you ask me.

This is a tempest in a teapot just like those mass "Quit Facebook" protests that spring up every time the privacy settings change. The entire controversy exists because a tiny, yet incredibly vocal, minority makes a huge deal of it only to drop it the next week. And from reading write ups on freemium services, the vocal minority is also part of the non-paying majority.
Dropbox has a technically exploitable feature which they don't want passed around for file sharing purposes so they stopped their own servers from helping. Big whoop.
I no longer like what they're doing, so the gravy train stops.
