The difference there is that Vuze doesn't in any way claim to not be doing the things it does. Also there are a million guides on the net about how to make it classic i.e. the old Azureus.

In Vuze it is not only possible to turn of automatic updates, but even selective automatic updates. And not only that, but álso what, when, how.

Unlike FrostWire the owners of Azureus/Vuze actually listen to what the end user wants.

Of course this is because of Private BitTorrent, where one wrong move will blacklist any client. This is something FrostWire devs never seemed to grasp. If you don't follow protocol, **** off!
