Well they couldn't push it into extras since it is a community reviewed approval process. But you are right, there's nothing stopping them from putting it on the internet for anyone to grab.

Piracy rates are high on every platform (even the iPhone). Having a closed app store system doesn't help you much, sure there may not be another way to get apps without jailbreaking, but look at the amount of information out there on jailbreaking and how many people were hit with that SSH vulnerability since most people just follow guides on how to jailbreak their phone without thinking about what the process is doing.

Though my concern more with the Ovi store isn't DRM at the moment (like I said it'll always be cracked. Try to use an IMEI #? People can change the IMEI #, etc..). But that it should be a setup system for handling transactions between the seller of the program and the buyer (regardless of what happens to the program after it's passed onto the buyer). And right now it's failing pretty badly at that if you can't afford to pay to go through their hoops.
