Starting a new thread, as the previous discussion about Ovi Store DRM has been locked.
The last comment in the old discussion is from wizard_hu_:
"I do not think that anyone would really spend much time on removing ads from fully functional, free applications."
That just happened to my Symbian application, only a few days after the release in Nokia Store. The free version is fully functional, but has a nag screen, with a link to purchase the paid version, when exiting. Googling with the application name, I found a version of the app with the nag screen removed and Russian translation (!). Also, there seems to be an unofficial Turkish translation out there.
However I don't see this kind of distribution as much of a problem, because the sis contents are modified and the original signing is no longer valid. This means that the users need a devcert or a hacked phone to install the packages, which rules out most ordinary users. Also, I even think it's quite cool that someone likes the application so much that he/she goes through the effort to translate it to another language
What I see as a big problem (as also stated by many in the original thread) is that it's so easy to take the original, signed sis files from Nokia store and freely distribute them. Anybody with Nokia Suite can install the app by simply double-clicking the file.
I'm wondering if it was at any point considered that the application sis files would be signed with the downloader's IMEI during the download process? This could maybe be done at least for files that use the Store's free signing, with Nokia provided UIDs. Symbian Signed website can be used to create devcerts without waiting, and no separate certificate installation is needed for those, so I don't see what the technical issues would be (except maybe more processing power needed for signing, and not being able to use the device web browser to download even free applications from Store, but who does that anyway?).
I'm not really expecting this kind of huge change to happen at this point, but just posting the idea for discussion.
