It would be better if trello had servers I could download, but they don't. I like their system, but I don't trust them with life details like bank account numbers and such. (though trello really isn't for that, see last paragraph)
That said, being the heavy FLOSS zealot that I am, I don't have a problem with what trello is doing, per say. They're offering a service, and paying for a service is fine. Particularly a well executed service with good support.
The service they offer isn't just access to an application, though it's a shame they keep that application to themselves, they offer a hosted server and storage for everyone to access. There's nothing morally wrong with it.
